CHAPTER VII.

Cosgrove’s Trip North

On leaving Cosgrove Ponson, Inspector Tanner walked slowly up the

shady side of Regent Street, his mind still running on the statement

to which he had just listened. To test its truth was his obvious first

duty, and as he sauntered along he considered the quickest and most

thorough means of doing so. From the very nature of the story he felt

inclined to believe it. Too much independent testimony seemed to be

available for the alibi to be a fraud.

And if this was so, he, Tanner, was on the wrong track, and was

wasting time. He had already lost nearly a week over Austin, and all

the time he was working on these blind alleys the real scent was

getting cold. But as he reviewed the facts he had learnt, he felt he

could hardly have acted otherwise than as he had.

He considered Cosgrove’s statement point by point. Firstly, was it

true he could only have gone to Scotland on the night in question of

all others? In answer to this it should be easy to find out if he

really was at the Duchess of Frothingham’s on the same afternoon. Then

the missing of the train at King’s Cross must be known to several

persons—the clerk at the stationmaster’s office, the barmaid who sold

the cigars, as well possibly as the sleeping-car attendant, and the

telegraph-office clerk, and copies of the wires to Grantham and to

Montrose should be available. He was not sure that confirmation of

Cosgrove’s visit to the Empire would be obtainable, though some

attendant might have noticed him. But there should be ample proof of

his call on Miss Belcher at the Follies Theatre. Not only would there

be the testimony of Miss Belcher herself, but some of the many

attendants must almost certainly have seen him. Then, if Cosgrove was

not actually seen leaving London by the 10.30 p.m., he must have been

observed in that train at Grantham, where his luggage was handed in to

him. Finally, to ensure that he did not leave the train there and

return to Luce Manor, as well as to test the genuineness of the whole

journey, Tanner could see Colonel Archdale, the horse owner of

Montrose.

And then another point struck him. What, he wondered, were the precise

relations between Cosgrove Ponson and Miss Betty Belcher? From their

demeanour at the restaurant, they were certainly on pretty intimate

terms. In this case could Miss Belcher’s testimony to Cosgrove’s call

at the theatre be relied on? Here was what undoubtedly might be a flaw

in the alibi, and he felt he must handle this part of it with special

care.

As he reached this point in his cogitations he arrived at the goal of

his walk—a small but extremely fashionable tobacconist’s in Oxford

Street. Handing in his card, he asked to see the manager.

He was shown into a small, neatly-furnished office, and there after a

few minutes a tall young man in a grey frock coat joined him.

‘Hallo, Tony,’ said the Inspector when the door had closed.

The newcomer greeted his visitor breezily.

‘Why, Tanner, old son,’ he cried, ‘how goes it? You’re a stranger, you

are. And what’s blown you in today?’

‘Business as usual. I want your help.’

‘You bet your life! And when you want help you know the right place to

come. Tony B won’t see you left, eh?’

‘I know that. You’re not as bad as you look.’

The other winked slowly.

‘And what’s little Albert’s trouble this time?’ he asked.

‘Why this,’ Tanner answered, taking out his two little boxes and

shaking the cigarette ends on to the table. ‘I want to know what kind

of cigarettes these are, and when they were smoked.’

‘H’m. Think I’m a blooming crystal-gazer, do you? Or one of those

Zancigs—what do you call ’em?’

As he spoke he was examining the ends with a strong glass. Then he

smelt them, drew out a shred of tobacco from each and tasted it, and

finally picked them up and took them out of the room.

‘Sit tight, Albert,’ he remarked as he left, ‘and keep your little

hands out of mischief till daddy comes back.’

In a few minutes he re-entered and laid the ends down on the table

with beside them a whole cigarette of a dark yellow colour.

‘There you are, sonny,’ he announced. ‘All chips of the old block,

those are.’

‘And what are they?’ Tanner queried, examining the little brown tube

with interest.

‘Costly rubies, rich and rare,’ his friend assured him. ‘They’re what

we call “Muriquis,” and they’re made in Rio by a firm called Oliveira.

There ain’t many in this village, I tell you. Who are you trailing

now? Is it Henry Ford or only his Majesty the King?’

‘Neither,’ Tanner returned seriously, ‘it’s that Ponson case I’m on.’

‘Never heard of it. But Ponson knows his way about in cigarettes

anyway, you bet your life.’

‘And how long since they were smoked? Can you tell me that?’

‘Nope. Not Tony B. This one about an hour; this one about a week at a

guess. But don’t you take all you hear for gospel. I don’t know, as

the girl said when her lover proposed.’

Tanner, though more bored with his friend’s conversation every time he

met him, remained chatting for some minutes. The two men had been at

school together, and the Inspector kept up the acquaintanceship

because of the valuable information he frequently got on matters

connected with tobacco. But as soon as possible he took his leave,

breathing a sigh of relief when he found himself once more in the

street.

His interest was considerably aroused by the news he had just

received. The suspicions he had entertained of Cosgrove had been

somewhat lulled to rest by the latter’s story. But the fact that the

cigarette-end found in the boathouse at Luce Manor was of that same

rare kind which Cosgrove smoked revived all his doubts, and made him

more than ever resolved to test the alibi to the utmost limit of his

ability.

Before leaving Halford, Tanner had written to the photographers whose

names he had found on the prints in the drawing-room at Luce Manor,

ordering copies of Sir William’s, Austin’s, and Cosgrove’s

photographs. The studio was in Regent Street, and hailing a taxi,

Tanner drove there. The photographs were ready, and he put one of each

in his pocket. Also he selected prints of three or four other men as

like in appearance to the cousins as he could find. Then he went on to

the Duchess of Frothingham’s house in Park Lane.

He saw her Grace’s butler, and representing himself as a reporter on

the staff of a well-known society journal, asked for a list of the

guests present at the ‘At Home’ on the Wednesday of the murder,

discreetly insinuating that he was prepared to pay for the trouble

given. The addendum had the desired effect, and after a considerable

delay a copy of the list was in Tanner’s hands. A glance at it showed

Cosgrove’s name among the others, and a few judicious questions

established the fact that he had actually been present.

Once more in the street, Tanner looked at his watch. It was after six

o’clock.

‘A little dinner and then the Empire,’ he said to himself as he turned

into Piccadilly. He had decided his first step must be to apply to

those sources of information which could not possibly be interested in

Cosgrove’s affairs; afterwards, if need be, hearing what Miss Belcher

had to say on the same subject.

A couple of hours later he reached the Empire. Here he made exhaustive

inquiries, but without finding anyone who had seen his man. But he was

not greatly disappointed, as he had already realised that confirmation

of this part of the alibi was problematical, if not unlikely.

Returning to his taxi, he continued his journey till he reached King’s

Cross. It was just nine o’clock, and the great station was partially

deserted, there being a lull in the traffic about that hour. For the

first time that day Tanner felt cool, and he began to realise that he

was tired. But apart from the general urgency of his business, he

expected the persons he wished to see were on evening duty, and he

decided he must finish his inquiries then and there. He therefore went

to the stationmaster’s office, and sent in his card. A dark,

intelligent looking young man with an alert manner received him, and

to him Tanner explained his business.

‘I did hear something about it,’ the young man returned. ‘If you will

wait a moment I’ll make inquiries.’

He left the room, returning presently with a clerk.

‘Mr Williams here remembers the affair. He dealt with it. Tell this

gentleman what you know, Williams.’

‘On Wednesday evening, the 7th instant, about 7.20 or 25,’ began

Williams, ‘a man called at the office and said he had booked a berth

to Montrose on the 7.15 p.m., but that he had missed the train while

in the refreshment room. He said his suit-case and waterproof had gone

on in the train, and he asked what I would advise him to do.’

‘That’s the man,’ said Tanner, nodding. ‘Yes?’

‘I told him the trains. The next to Montrose was the 10.30 p.m., and

his mistake only meant that he would reach there at 8.24 a.m. instead

of 5.25. But it seemed he wanted to arrive early, and I mentioned the

8.30 p.m. which runs from here to Dundee, suggesting he could go on by

car. But on going into it he decided even this would be too late, and

said he would travel on the 10.30. With regard to his luggage I

offered to wire Grantham, which is the first stop of both the 7.15

p.m. and the 10.30, to have it collected from the sleeping car on the

7.15 p.m., and put into the 10.30. He agreed to this, and I sent the

telegram at once.’

‘Would you know the man if you saw him again?’

‘Yes, I believe I should.’

‘Any of these he?’ and Tanner handed over the half-dozen photographs.

The clerk instantly passed over Sir William’s and those of the

strangers, then he examined Austin’s for some moments with a puzzled

expression, but when he came to Cosgrove’s he hesitated no longer.

‘That’s the man,’ he said, repeating Tanner’s words of a moment

before, ‘I should know him anywhere.’

‘So far so good,’ thought Tanner as he stepped out once more on to the

concourse. ‘Now for the refreshment room.’

He found the platform from which the 7.15 had started on the night in

question, and looked about him. There was little doubt as to where

Cosgrove had gone for his cigars. On the platform itself was a large

sign ‘First-Class-Refreshment Room.’ The Inspector pushed open the

door and entered.

‘Good evening,’ he said, raising his hat politely to the presiding

goddess. ‘I want a few cigars, please.’

‘I have only these,’ the girl answered, placing two partially emptied

boxes before him.

Tanner examined them.

‘I am not much of a judge,’ he informed her, ‘but these look the

lighter. I’ll have half a dozen, please. That is,’ he went on with a

whimsical glance at the clock, ‘if it’s safe.’

The barmaid looked at him as if she thought he was crazy, but she did

not speak and Tanner explained:

‘A friend of mine had an experience here the other night buying

cigars, so he told me. He missed his train over the head of it. I was

wondering if I should do the same.’

A light seemed to dawn on the girl. She laughed.

‘I remember your friend. I couldn’t help smiling, but I was sorry for

him too. He came in here and chose a dozen cigars, and then he looked

up and saw the clock.

‘“Your clock’s fast,” he says.

‘“I _don’t_ think,” I says, and with that he hooked it out of the

door, fair running, and all the cigars lying on the counter. I

couldn’t but laugh at him.’

‘But _he_ didn’t laugh, for he missed his train,’ prompted Tanner.

‘Oh, he missed his train right enough. He came back and showed me his

watch—three minutes slow. But he got his cigars all right.’

Tanner took Austin’s photograph from his pocket, and glancing at it

casually, passed it to the girl.

‘He’s a good old sport, he is,’ he announced, ‘but to look at him

there you wouldn’t think butter would melt in his mouth. What do you

say?’

The girl wrinkled her pretty eyebrows.

‘But that isn’t the man,’ she exclaimed.

Tanner took the card.

‘I’m a blooming idiot,’ he said. ‘I’ve shown you the wrong photo. This

was the one I meant.’ He handed over the print of Cosgrove.

‘Why, yes,’ the girl answered unhesitatingly. ‘That’s him and no

mistake.’

‘He’s a good soul enough,’ went on Tanner, ‘but he was very sick about

that train, I can tell you.’

They conversed for a few moments more as the Inspector lit one of his

purchases. Then with a courteous ‘Goodnight,’ he left the bar.

Whatever else might be true or false in Cosgrove’s statement, thought

Tanner, it was at least bed rock that he had missed the 7.15 train as

he had said. The thing now to be ascertained was whether he really had

travelled by the 10.30.

By dint of persistent inquiries the Inspector found a number of the

men who had been on duty when that train left. But here he was not so

successful. No one so far as he could learn had seen Cosgrove.

But this was not surprising. Tanner could not and did not expect

confirmation from these men. They had had no dealings with Cosgrove

which would have attracted their attention to him. The point could be

better tested at Grantham, where whoever gave him his luggage should

remember the circumstance.

Inspector Tanner glanced at the clock. It was ten minutes to ten. Why,

he thought, when he was so far, should he not carry the thing through

right then? He looked up the time tables. A train left at 10.00 p.m.

for Grantham, arriving at 12.28. The 10.30 p.m., following, reached

the same station ten minutes later, proceeding at 12.43. If he went by

the 10.00 he would have fifteen minutes at Grantham to make inquiries,

and he could go on by the 10.30 to Montrose and interview Colonel

Archdale. And if fifteen minutes proved insufficient for his Grantham

business he could sleep there, and go on in the morning.

Five minutes later he was in the train. Though, compared to that

following, it was a slow train, it only made four stops—at Hatfield,

Hitchin, Huntingdon and Peterborough. A minute before time it drew up

at Grantham.

Here Tanner had even less difficulty than at King’s Cross. An official

at the stationmaster’s office remembered the episode of the telegram,

and was able in a few seconds to find the porter to whom he had

entrusted the matter. This man also clearly recollected the

circumstances and unhesitatingly identified Cosgrove from his

photograph.

‘Just tell me what occurred when you met Mr Ponson, will you?’ asked

Tanner.

‘Well, sir,’ the man answered, ‘I was going along the train with ’is

bag and coat, and ’e comes out of a first-class carriage bare ’eaded,

and when ’e sees the bag ’e says, “that’s my bag, porter,” ’e says,

and ’e gives ’is name. “Shove it in ’ere,” ’e says. ’E ’ad ’is ’at on

the seat for to keep ’is place, and that’s all I knows about it.’

The confirmation seemed so complete that Tanner was tempted to return

to town instead of taking the long journey to Montrose. But before

everything he was thorough. He had paid too dearly in the past for

taking obvious things for granted. In this case every point must be

tested.

Soon, therefore, he was moving slowly out of Grantham on his way

north. He had not been able to get a sleeping berth, but he made

himself as comfortable as possible in the corner of a first-class

compartment, and there he slept almost without moving till the bustle

at Edinburgh aroused him. Here a restaurant car was attached, and

shortly after Tanner moved in and breakfasted.

At Montrose he went to a barber’s and was shaved, then, hiring a car,

he was driven out to the training stables.

Colonel Archdale was an elderly man of a school Tanner had imagined

was extinct—short, red-faced and peppery, and dressed in a check suit

and riding breeches. The Inspector had called at the house, a low,

straggling building of the bungalow type, but had been sent on to find

its master at the stables, half a mile distant.

‘Mornin’,’ the Colonel greeted him, as Tanner handed him his card and

asked for a few moments conversation. ‘Certainly, I’ll go up to the

house with you in a minute.’

‘I shouldn’t, sir, dream of troubling you so far,’ Tanner assured him.

‘Besides, it is not necessary. A minute or two here when you are

disengaged is all I want.’

‘Be gad, sir, you’re modest. Comin’ all the way from London for a

minute or two,’ and calling out some directions to a groom, he led the

way into a kind of small office at the end of the stable.

‘Well, sir,’ he said as he seated himself before a small roll top

desk, and pointed to a chair, ‘and what can I do for you?’

‘I am engaged, sir,’ Tanner answered, ‘in making some confidential

inquiries into the movements of a man, who, I understand, was recently

here—Mr Cosgrove Ponson of London.’

‘He was here’—the Colonel hesitated a moment—‘this day week. And what

the devil has he been doin’?’

‘Nothing, sir, so far as we know. It is the case of another man

altogether, but it is necessary for us to know if Mr Ponson really was

out of London on that day.’

‘Well I’ve told you he was here. Is that evidence enough?’

‘Quite, sir, as far as that goes. But I would like also to know some

details to assure myself if his business here was genuine. What was

his business, if I might ask?’

‘You may ask and I’ll tell you too, be gad. He wanted to see Sir

Jocelyn, that’s a three-year-old I’m goin’ to sell. Devilish good bit

of horseflesh too. But he wouldn’t stretch to my figure. I wanted

seven hundred, and he would only go five fifty. So it was no deal.’

‘He came about this time in the morning, I suppose?’

‘Yes, and a confoundedly silly time it was to come. He was to have

been here at six for the morning exercise, but he missed his train, so

he said, in London.’

‘I understood so from him. Just one question more, sir. When was the

arrangement about his visit made?’

‘Some days before; I think it was on Monday evening I got his wire

asking would Thursday suit me.’

‘This is the man you mean, I presume?’ and Tanner took out Cosgrove’s

photograph.

The colonel nodded as he answered: ‘That’s he.’

‘And there was nothing, sir, in the whole episode that seemed to you

suspicious or otherwise than it appeared on the surface?’

‘Not a thing.’

Tanner rose.

‘Allow me then, sir, to express my thanks for your courtesy. That is

all I want to know.’

Declining an invitation to go up to the house for a drink—‘too

devilish risky to keep it here, be gad’—he returned to Montrose and

looked up the trains to London. There was one at 2.29 which,

travelling by Edinburgh and Carlisle, reached St Pancras at 6.30 the

following morning. This, he decided, would suit him admirably, and

when it came in he got on board.

As he sat a little later gazing out on to the smiling Fifeshire

country, he went over once more, point by point, that portion of

Cosgrove’s alibi which he had already checked. So far as he had gone

it certainly seemed to him very complete. In the first place, not only

was the journey north made with, so far as he could ascertain, a quite

genuine purpose, but the selection of that particular night was

reasonably accounted for. The arrangement for it had been made at

least as early as the previous Monday, which, again, would be a

reasonable time in advance. Tanner could see nothing in any way

suspicious or suggestive of a plant about the whole business.

Then, coming to details, the missing of the train at King’s Cross

might of course have been faked, but there was no evidence to support

such a supposition. On the contrary, everything he had learnt seemed

to prove it genuine. But even if it had been a plant, it was

demonstrated beyond a shadow of doubt that Cosgrove _had_ missed the

7.15 p.m. as he said, and that, further, he _had_ travelled to

Montrose by the 10.30. Even as the case stood Tanner felt bound to

accept the alibi, but if he could confirm Cosgrove’s statement of his

visit to his rooms at 7.45 or 8 o’clock, and to the Follies about

10.00, any last shred of doubt that might remain must be dispelled.

This, he decided, would be his next task.

The following morning, therefore, he returned to Knightsbridge. Here,

keeping his eye on Cosgrove’s door, he strolled about for nearly an

hour before he was rewarded by seeing it open and Cosgrove emerge and

disappear towards Piccadilly. He allowed some ten minutes more to

elapse, then he walked to the door and rang. It was opened by the same

dark, clean-shaven butler who had admitted him before. The man

recognised his visitor, evidently with suspicion.

‘Mr Reginald Willoughby, the Albany?’ he asked with sarcasm, and a

thinly veiled insolence in his tone.

‘That’s all right,’ Tanner answered easily. ‘I know my name is not

Willoughby. It’s Tanner’—he handed over his real card—‘and if you’ll

invite me in for a moment or two I’ll show you my credentials so that

you’ll have no more doubt.’

The butler was evidently impressed, and proffering the suggested

invitation, led the way to a small sitting room.

‘Mr Ponson he phoned the Albany,’ he explained, ‘and they said there

weren’t no one of that name there, so we was wondering about your

little game.’

Tanner, following his usual custom, rapidly sized up his man, and

decided how he should deal with him. With the veneer of his calling

removed the Inspector imagined he might prove a braggart, a bully, and

a coward. He therefore took a strong line.

‘I suppose you know,’ he began, without heeding the other’s remark,

‘that Mr Cosgrove Ponson is under serious suspicion of the murder of

his uncle, Sir William, at Luce Manor?’

It was evident this was the last thing the butler had expected to

hear. He stared at the Inspector in amazement.

‘Lord lumme!’ he stammered, ‘is that a fact?’

‘That’s a fact,’ Tanner went on sharply, ‘and I want some information

from you. And let me advise you to give it to me correctly, for if you

don’t you may find yourself in the Old Bailey charged as an accessory

after the fact.’

The man blenched, and Tanner felt that the estimate he had made of his

character was correct.

‘I don’t know nothing about it,’ he growled sulkily.

‘Oh yes, you do. Mr Ponson told me he spent that Wednesday night here,

or a part of it anyway. Is that true?’

Tanner had set his little trap to learn whether the butler had been

primed with a story by Cosgrove. His victim did not answer for a time.

Clearly a struggle was going on in his mind. Then at last he said,

‘Has Mr Cosgrove been arrested?’

The question still further bore out the estimate Tanner had made of

the man’s character. The Inspector could follow the thought which had

prompted it. If the butler was to continue uninterruptedly in his

master’s service, he would rather not have the latter know he had

given him away, but if Cosgrove was already in custody he would keep

on the safe side and tell the truth. Tanner did not assist him to a

conclusion.

‘Never you mind that. You concentrate on avoiding arrest yourself.

Now, will you answer my question?’

After some further urging the statement came. Cosgrove had not spent

the evening in his rooms. He had left about 6.45 to catch the 7.15 at

King’s Cross, but he had returned unexpectedly in about an hour. He

told the butler he had missed his train, and was travelling by a later

one. He had gone out again, almost at once, and the butler had not

seen him for two days.

Tanner asked several searching questions, and ended up completely

satisfied that the man was telling the truth. There was no doubt

whatever that Cosgrove’s story was true in this particular also.

There now remained to be checked only the matter of his visit to the

Follies, and though Tanner was not certain of the necessity for this,

his habit of thoroughness again asserted itself, and he drove to the

theatre. There he learnt that there was no rehearsal that forenoon,

and he went straight on to Chelsea. His ring at the actress’s flat was

answered by a smartly dressed maid, to whom he handed his card, asking

for an interview with her mistress.

The girl disappeared and in a few moments returned.

‘Miss Belcher will see you now, sir.’

He was ushered into a small drawing-room, charmingly furnished in pale

blue, with white enamelled woodwork. The chairs were deep and

luxurious though elegant, the walls panelled with silk and bearing a

few good monochrome drawings, while on the dark polished floor were

thick and, as the Inspector knew, costly rugs. But though everything

in the room was dainty, its outstanding feature was its roses. Roses

were everywhere, massed in great silver bowls and rare old cut-glass

vases.

‘It’s a rose case,’ thought the Inspector whimsically, as he recalled

that in two other sitting rooms he had had to visit—those of Miss Lois

Drew and Cosgrove Ponson—he had found the same decoration, though in

neither case with the same prodigal liberality as here.

He waited for over half an hour and then the door opened and Miss

Belcher appeared.

Seeing her full face in the light from the window, he realised her

beauty as he had not done in the restaurant. Though she was

slightly—Tanner thought comfortable looking, though jealous people

might have used the word stout—her features were so delicately

moulded, her little, pouting mouth so daintily suggestive of dimples,

her light blue eyes so large and appealing, her complexion so creamy,

and above all and crowning all, her hair, so luxuriant and of so

glorious a shade of red gold, that he began to understand the position

she held in the popular favour. She was dressed in a garment which

Tanner imagined was a _négligé_, a flowing robe of light-blue silk

trimmed with the finest lace, beneath which peeped out the tiny toe of

a gilt slipper.

Tanner bowed low.

‘I beg you to pardon this intrusion, madame,’ he said, ‘but my

business is both serious and urgent.’

Without speaking, the actress sank gracefully into a luxurious

arm-chair, indicating with a careless wave of her arm a seat for the

Inspector in front of her. He obeyed her gesture and continued:

‘I have been ordered, madame, to make an investigation into the death

of the late Sir William Ponson of Luce Manor, not far from Luton. I

understand that you are acquainted with his nephew, Mr Cosgrove

Ponson?’ His hostess nodded, still without speaking. Tanner thought

her manner unnecessarily ungracious, and determined to give a hint of

the iron which lurked beneath his velvet exterior.

‘I deeply regret to have to inform you that there is reason to believe

Sir William was murdered, and that grave suspicion rests on Mr

Cosgrove.’

This time the mask of indifference was pierced.

‘But how perfectly outrageous,’ the lady cried, a flicker of anger

passing over her expressive face, ‘and stupid and cruel as well. How

dare you come here and tell me such a thing?’

‘Because I think you may help me to clear him. Please consider the

facts. The medical evidence shows Sir William was murdered some time

after 8.30 on the evening of Wednesday week. We know that Mr Cosgrove

Ponson was financially in low water—in fact, was in debt for a very

large sum, and under threat of exposure and ruin unless he paid up. We

know also he benefited to a considerable extent under Sir William’s

will. Further, in the boathouse from which Sir William’s body was set

adrift, a cigarette end was found—one of a peculiar brand, but little

smoked in England, but which Mr Ponson continually uses, and lastly,

and this is what brings me to you today, Mr Ponson has been unable to

account satisfactorily for his time on the evening in question. He

says he was with you from 8.30 till 9.00, and what I want to ask you

is, Can we get proof of that? I think you will appreciate that proof

of that means proof of his innocence.’

Tanner had been unobtrusively watching his companion while he spoke,

and her demeanour interested him keenly. While he was recounting the

medical evidence and Cosgrove’s financial position she had listened

perfunctorily, as if bored by such trifles being brought to her

notice. But when he mentioned the cigarette she started and a look

first of fear and then of anger showed momentarily in her eyes. It

seemed to Tanner she might have so acted if she knew Cosgrove was

guilty—as if she was aware of and prepared for all he had to say

except this about the cigarette, and that her anger was against

Cosgrove for having smoked under such circumstances. She did not speak

for some moments, and Tanner felt instinctively she had seen his

little trap, and was considering a way out. At last she appeared to

come to a conclusion, and replied in a quiet voice:

‘What Mr Ponson has told you is quite true, or at least almost. He was

at my room at the Follies for about half an hour that evening, but not

quite at the hour you have mentioned. He came about half-past nine,

and left at ten. I know the time because it is the only period in that

play during which I am off the stage.’

She had avoided his trap anyway, and her answer confirmed Cosgrove’s

story. But Tanner recognised he was dealing with a very clever woman,

and he was by no means so convinced of the truth of her statement as

he was of that of the butler. He went on:

‘Obviously, madame, if we have to go before a jury the more

corroborative evidence we can get the better. Now, are there any other

persons who might have seen Mr Ponson at the theatre, and who could be

called to add their testimonies?’

‘I don’t know if anyone else actually saw Mr Ponson,’ she answered,

‘but I should think it likely. Probably the door-keeper did, or one of

the other men. Have you made inquiries?’

‘No, madame. Not yet.’

‘Well, you had better do so,’ and she got up to indicate that the

interview was at an end.

Tanner found himself in the street with a baffled feeling of having

handled the interview badly. But it was at least obvious that the

lady’s advice was good, and somewhat ruefully he drove back to the

Follies.

Here he made exhaustive inquiries, but without any very satisfactory

result. The stage door-keeper knew Cosgrove, and said he was a

frequent visitor to Miss Belcher. He remembered he had come two or

three evenings in the week in question at about 9.30, and stayed with

the actress for about half an hour. But he could not be sure whether

or not Wednesday was one of these evenings. Three or four other

attendants had also seen him, but in no case had there been anything

to attract their attention to him, and none of them could say on what

nights he had been there. But Tanner had to admit to himself that he

could hardly expect such information from persons who were not

interested in Cosgrove’s visit.

But on another point he got positive information. His inquiries

established the fact that on the Wednesday night of the murder Miss

Belcher had been on the stage at 9.15. She therefore could not have

been masquerading as Mrs Franklyn’s servant at the Old Ferry.

On the whole the Inspector felt that, in spite of his momentary

suspicion of Miss Belcher’s manner, he must fully accept the alibi.

The evidence of Cosgrove’s missing the 7.15 p.m. train, and travelling

by the 10.30 was overwhelming. The butler’s corroboration of his

master’s return to Knightsbridge was convincing. Though Tanner was not

so sure of Miss Belcher’s statement, it at least agreed with

Cosgrove’s. Further, the lady had not fallen into Tanner’s little trap

about the hour of the call and had disagreed with what he told her

Cosgrove had said.

Then another point struck him. Cosgrove was at Knightsbridge between

7.45 and 8.00, and at King’s Cross at 10.30. Was this evidence alone

not sufficient? Would it have been possible for him to have visited

Luce Manor in the interval? Suppose he had used a fast motor and gone

by road?

Tanner did not think it could have been done. From London to Halford

was thirty-five miles, and there and back made seventy. What speed

could he reckon on? Considering how much of London would have to be

traversed, and the amount of traffic to be expected on so important a

road, Tanner felt sure not more than an average of thirty miles an

hour at the outside. This would take two hours and twenty minutes at

least, leaving from ten to twenty minutes. The motor never would have

risked going up to Luce Manor, as it would have been heard—in fact, no

motor did so. That meant that ten minutes must have been spent in

going from the road to the boathouse, and another ten in returning.

This even if it could be done at all, would leave no time in which to

commit the murder, get out the boat and set the body and the oars

adrift. Tanner considered it carefully, and at last came to the

conclusion the thing would be utterly impossible. Indeed, he did not

believe that an average of thirty miles an hour could be maintained.

No, the alibi was complete. He felt he must unhesitatingly accept it.

Inspector Tanner was a depressed man as he walked slowly back to New

Scotland Yard. Up to the present he saw that he had been on the wrong

track—that all his time and trouble had been lost. He was now as far

off solving the mystery, as when he started the inquiry, indeed

further, for the real scent must now be cooler.

And Sergeant Longwell had been almost equally unsuccessful in his

endeavour to trace the man who had made the fifth line of footprints

on the river bank. With occasional assistance from Tanner the sergeant

had made exhaustive inquiries in all the surrounding country, but

without result. The only thing he had learnt which might have had a

bearing on the matter was that a small, elderly man with a white

goatee beard had taken the 5.47 a.m. train from St Albans to London,

on the morning of the discovery of the crime. From Halford to St

Albans was about fifteen miles, and Longwell’s theory was that this

man—if he were the suspect—had walked during the night to St Albans,

thinking that at a large station a considerable distance from Luce

Manor he would be more likely to escape observation. But there was no

real reason to connect this early traveller with the visitor to the

boathouse. His boots had not been observed. But even if it had been

proved that he was indeed the wanted man, the detectives were no

further on. For the traveller had vanished into thin air at St Albans,

and no trace of him could be found either in London or anywhere else.

That day a note was received at the Yard from the Chief Constable at

Halford, urging that, unless there was some strong reason for its

further adjournment, the inquest should be completed. The delay, it

was pointed out, was objectionable for several reasons, as well as

being needlessly trying to the family. Rather bitterly Tanner wired

his consent to the proposal, and later in the afternoon there was a

message that the adjourned inquiry would take place at 12.00 noon next

day, Saturday.
