CHAPTER XXVI

"This is a remarkable story, Mr. Colwyn," said the chief constable,

breaking the rather lengthy silence which followed the conclusion of the

detective's reconstruction of the crime. "It has been quite entrancing

to listen to your syllogistical skill. You would have made an excellent

Crown Prosecutor." The chief constable's official mind could conceive no

higher compliment. "Your statements seem almost too incredible for

belief, but undoubtedly you have made out a case for the further

investigation of this crime. What do you think, Galloway?"

"The question, to my mind, is what Mr. Colwyn's discoveries really

represent," replied Galloway. "He has built up a very ingenious and

plausible reconstruction, but let us discard mere theory, and stick to

the facts. What do they amount to? Apart from Penreath's statement in

the gaol that he saw the body carried down stairs----"

"You can leave that out of the question," said the detective curtly. "My

reconstruction of the crime is independent of Penreath's testimony,

which is open to the objection that it should have been made before."

"Exactly what I was going to point out," rejoined Galloway bluntly.

"Well, then, let us examine the fresh facts. There are five as I see

them. The recovery of Penreath's match-box, the discovery of the door

between the two rooms, the wound on the innkeeper's forehead, the

additional key, and the finding of the pocket-book in the pit. Exclude

the idea of conspiracy, and the recovery of the match-box becomes an

additional point against Penreath, because it strikes me as guess work

to assume that he had no other matches in his possession except that

particular box and the loose one he found in his vest pocket. Smokers

frequently carry two or three boxes of matches. The discovery of the

hidden door is interesting, but has no direct bearing on the crime. The

wound on the innkeeper's head looks suspicious, but there is no proof

that it was caused by his knocking his head against the gas globe in the

murdered man's room on the night of the murder. As Mr. Colwyn himself

has pointed out, there is not much in Benson having a second key of

Glenthorpe's room. Many hotel-keepers and innkeepers keep duplicate keys

of bedrooms. The significance of this discovery is that Benson kept

silence about the existence of this key. Undoubtedly he should have told

us about it, but I am not prepared to accept, offhand, that his silence

was the silence of a guilty man. He may have kept silence regarding it

through a foolish fear of directing suspicion to himself. That theory

seems to me quite as probable as Mr. Colwyn's theory. There remains the

recovery of the money in the pit. In considering that point I find it

impossible to overlook that Penreath returned to the wood after making

his escape. That suggests, to my mind, that he hid the money in the pit

himself, and took the risk of returning in order to regain possession of

it."

"You are worthier of the chief constable's compliment than I, my dear

Galloway," said Colwyn genially. "Your gift of overcoming points which

tell against you by ignoring them, and your careful avoidance of

tell-tale inferences, would make you an ideal Crown Prosecutor."

"I don't believe in inferences in crime," replied Galloway, flushing

under the detective's sarcasm. "I am a plain man, and I like to stick to

facts."

"What was the whole of your case against Penreath but a series of

inferences?" retorted Colwyn. "Circumstantial evidence, and the

circumstances on which you depended in this case, were never fully

established. Furthermore, your facts were not consistent with your

original hypothesis, and had to be altered when the case went to trial.

Now that I have discovered other facts and inferences which are

consistent with another hypothesis, you strive to shut your eyes to

them, or draw wrong conclusions from them. Your suggestion that Penreath

must have hidden the money in the pit because he was arrested near it is

a choice example of false deduction based on the wrong premise that

Penreath hid the money there on the night of the murder. He could not

have done so because he had no rope, and how was he, a stranger to the

place, to know that the inside of the pit was covered with creeping

plants of sufficient strength to bear a man's weight? The choice of the

pit as a hiding place for the money argues an intimate local knowledge."

"You have not yet told us how you came to deduce that the money was in

the pit," said Mr. Cromering, who had been examining the pocket-book and

money.

"While I was examining the mouth of the pit the previous afternoon I

found this piece of paper at the brink, trodden into the clay. Later on

I recognised the peculiar watermark of waving lines as the Government

watermark in the first issue of Treasury war notes. From that I deduced

that the money was hidden in the pit. It was all in Treasury notes, as

you see."

"I'm afraid I don't quite follow you now," said the chief constable,

with a puzzled glance at the piece of dirty paper in his hand. "This

piece of paper is not a Treasury note."

"Not now, perhaps, but it was once," said the detective with a smile.

"It puzzled me at first. I could not account for the Treasury watermark,

designed to prevent forgery of the notes, appearing on a piece of blank

paper. Then it came to me. The first issue of Treasury notes were very

badly printed. Ordinary black ink was used, which would disappear if the

note was immersed in water. It was an official at Somerset House who

told me this. He informed me that they had several cases of munition

workers who, after being paid in Treasury notes, had put them into the

pockets of their overalls, and forgotten about them until the overalls

came back from the wash with every vestige of printing washed out from

the notes, leaving nothing but the watermarks. It occurred to me that

the same thing had happened in this case. The murderer, when about to

descend to the pit to conceal the money, had accidentally dropped a note

and trodden it underfoot, and it had lain out in the open exposed to

heavy rains and dew until every scrap of printing was obliterated."

"By Jove, that's very clever, very clever indeed!" exclaimed Galloway.

He picked up a magnifying glass which was lying on the table, and

closely examined the dirty piece of white paper which Colwyn had found

at the mouth of the pit. "It was once a Treasury note, sure enough--the

watermark is unmistakable. You've scored a point there that I couldn't

have made, and I'm man enough to own up to it. You see more deeply into

things than I do, Mr. Colwyn. And I'm willing to admit that you've made

some new and interesting discoveries about this case, though in my

opinion you are inclined to read too much into them. But I certainly

think they ought to be investigated further. If Penreath's statement to

you this morning is true, Benson is the murderer, and there has been a

miscarriage of justice. But what makes me doubt the truth of it is

Penreath's refusal to speak before. I mistrust confessions made out at

the last moment. And his explanation that he kept silence to save the

girl strikes me as rather thin. It is too quixotic."

"There is more than that in it," replied Colwyn. "He had a double

motive. Penreath heard Sir Henry Durwood depose at the trial that he

believed him to be suffering from epilepsy."

"How does that constitute a second motive?"

"In this way. Penreath has a highly-strung, introspective temperament.

He went to the front from a high sense of duty, but he was

temperamentally unfit for the ghastly work of modern warfare, and broke

down under the strain. Men like Penreath feel it keenly when they are

discharged through shell-shock. They feel that the carefully hidden

weaknesses of their temperaments have been dragged out into the light of

day, and imagine they have been branded as cowards in the eyes of their

fellow men. I suspect that the real reason why Penreath left London and

sought refuge in Norfolk under another name was because he had been

discharged from the Army through shell-shock. He wanted to get away from

London and hide himself from those who knew him. To his wounded spirit

the condolences of his friends would be akin to taunts and sneers. When

Sir Henry Durwood questioned him he was careful to conceal the fact that

he had been a victim of shell-shock. As a matter of fact, Penreath's

behaviour in the breakfast room that morning was nothing more than the

effects of the air raid on his disordered nerves, but he would sooner

have died than admit that to strangers. After listening to the evidence

for the defence at the trial, he came to the conclusion that he was an

epileptic as well as a neurasthenic. He might well believe that life

held little for him in these circumstances, and that conviction would

strengthen him in his determination to sacrifice his life as a thing of

little value for the girl he loved."

"If that is true he must be a very manly young fellow," said the chief

constable.

"Supposing it is true, what is to be done?" asked Galloway, earnestly.

"Penreath has been tried and convicted for the murder."

"The conviction will be upset on appeal," replied the detective

decisively.

"But I do not see that carries us much further forward as regards

Benson," persisted Galloway. "If he is the murderer, as you say, he will

clear out as soon as he hears that Penreath is appealing."

"He will not be able to clear out if you arrest him."

"On what grounds? I cannot arrest him for a murder for which another man

has been sentenced to death."

"True. But you can arrest him as accessory after the fact, on the ground

that he carried the body downstairs and threw it into the pit."

"And suppose he denies having done so? Look here, Mr. Colwyn, I want to

help you all I can, but if I have made one mistake, I do not want to

make a second one. Frankly, I do not know what to think of your story.

It may be true, or it may not. But speaking from a police point of view,

we have mighty little to go on if we arrest Benson. If he likes to bluff

us we may find ourselves in an awkward position. Nobody saw him commit

the murder."

"I realise the truth of what you say because I thought it all over

before coming to see you," replied Colwyn. "If Benson denies the truth

of the points I have discovered against him, or gives them a different

interpretation, it may be difficult to prove them. But he will not--he

will confess all he knows."

"What makes you think so?"

"Because his nerve has gone. If I had confronted him that night when I

saw him in the room I would have got the whole truth from him."

"Why did you not do so?"

"Because I had not the power to detain him. I am merely a private

detective, and can neither arrest a man nor threaten him with arrest.

That is why I have come to you. You, with the powers of the law behind

you, can frighten Benson into a confession much more effectually than I

could."

"I don't half like it," grumbled Galloway. "There's a risk about it----"

"It's a risk that must be taken, nevertheless." It was Mr. Cromering who

intervened in the discussion between the two, and he spoke with unusual

decision. "I agree with Mr. Colwyn that this is the best course to

pursue. I will go with you and take full responsibility, Galloway."

"There is no need for that," said Galloway quickly. "I am quite willing

to go."

"I will accompany you and Mr. Colwyn. It has been a remarkable case

throughout, and I want to see the end--if this is the end. I feel keenly

interested in this young man's fate."

"I should like to go also, but an engagement prevents me," said Mr.

Oakham. "I am quite content to leave Penreath's interests in Mr.

Colwyn's capable hands." He rose as he spoke, and held out his hand to

the detective. "We have all been in error, but you have saved us from

having an irreparable wrong on our consciences. I cannot forgive myself

for my blindness. Perhaps you will acquaint me with the result of your

visit when you return. I shall be anxious to know."

"I will not fail to do so," replied Colwyn, grasping the solicitor's

hand. "We had better catch the five o'clock train to Heathfield and walk

across to Flegne," he added, turning to the others. "It will be as quick

as motoring across, and the sound of the car might put Benson on his

guard. We want to take him unawares."

"He'll have got wind of something already if he finds the pocket-book

gone," said Galloway. "He may have bolted while we have been talking

over things here."

"I've seen to that," replied the detective. "I tied my own pocket-book

to the fishing line in the pit, and left Queensmead watching the pit. If

Benson tries to escape with my pocket-book Queensmead will arrest him

for robbery. I've made a complaint of the loss."

"You haven't left much to chance," replied Galloway, with a grim smile.
