CHAPTER IX

ICE CREAM SODA

They drove in silence to headquarters, each man busy with his thoughts.

It was not until they were alone in Leverage's sanctum that the subject

of the recent interview was again broached. It was Leverage who brought

it up, in his characteristically gruff way.

"I reckon you're wonderin', Carroll, about what I said back yonder

in the car?"

"About arresting Barker?"

"Yes. I guess you're figuring what I'd arrest him for, eh?"

"I'm interested--yes."

"I'd arrest him for this." Leverage leaned forward earnestly, his

attitude that of a man eager to convince. "Let's admit right off the reel

that the skirt in the taxicab croaked Warren. Looks like she did, anyway;

but whether she did or not, it's an even bet that there was a man mixed

up in it somewhere. And if that man isn't Mr. William Barker, then I'll

eat a month's pay."

"You're sure there was a man mixed up somewhere?"

"Certainly. This murder deal was planned in advance. It must have been.

Things couldn't just work out that way. And no woman, no matter how much

she wanted to bump Warren off, could think of a thing that complicated.

Even if she did think of it, she wouldn't have the nerve to carry it out

that way. Ain't I right?"

"You may not be right, Leverage; but you're certainly logical."

"Good! Now, so far, we ain't got any man in this case except Barker."

Carroll shook his head.

"You're wrong there."

"How?"

"Somewhere in this town is some man who is interested in the woman with

whom Warren was planning to elope. Don't forget this, Leverage--I let

Barker ramble on. I like to hear 'em talk. The minute he jumped at the

idea that the woman in the taxi was Miss Gresham, I knew perfectly well

that he knew she was not. I also believe that he knows who the woman

was. Further, I believe that she is socially prominent. That being the

case, it is a safe guess that there is some man who might commit a

murder, provided he knew in advance of the elopement. Our task now is to

discover that woman and, through her, the man interested."

Leverage frowned thoughtfully.

"Listens good," he volunteered at length. "Another thing--Barker admits

he was shooting pool in Kelly's place last night around midnight; and

Kelly's place is only half a block from the Union Station. That sounds

significant!"

"It does; and then again it may mean nothing. What I am striving for is

to make William Barker feel that he is safe. The safer he feels, the more

readily he will talk. No matter how many lies he tells, everything that

he says is of value. He didn't know, of course, that we already had a

perfect alibi for Miss Gresham; but even if we hadn't, his assumed belief

that she committed the crime would have assured me that she did not.

No-o, I think we'd better not arrest the man unless he forces our

hand--tries to jump town, or something like that. Better let him remain

at large and talk frequently. If he has anything to betray, there's more

chance that he'll do it that way. Don't you think I'm right?"

"I wouldn't admit it if I didn't, Carroll. I've seen you in action too

often to believe you're ever wrong."

Carroll flushed boyishly.

"Don't be absurd, Leverage! I'm often wrong--very wrong. And don't think

that I'm a transcendent detective; they don't really exist, you know. I'm

merely trying to be human, to learn the nature of the people with whom

I'm dealing. I try to learn 'em as well as they know themselves--maybe a

little better; and then I try to separate the wheat of vital facts from

the chaff of the inconsequential."

"Just the same," insisted Leverage loyally, "you always get 'em!"

"And when I do, it is because I have used nothing more than plain common

sense. Don't think that I attach no importance to physical clues. They're

immensely valuable; but the one weakness in a criminal is his lack of

common sense. His perspective is awry, his sense of values distorted.

Usually he bothers his head about a myriad minor details, and pays but

scant attention to the genuinely important things. It is upon that

weakness that I am banking--particularly so in the case of Barker."

"I insist that you're a wonder, Carroll!"

"And I insist that you're foolishly complimentary. Did you ever stop to

realize, Eric, that when a crime is committed the advantage lies entirely

with the detective? The detective can make a thousand mistakes during the

course of his investigations and still trap his man; but the criminal

cannot make one single error--not _one_!"

"Maybe so, David; but it takes a good man to recognize that one, and to

know what to do with it."

Carroll grinned and left, and then for two days devoted himself to a

study of the conditions surrounding the murder--that and routine matters.

The trunk, for instance, was duly returned by the railroad from New York,

and Carroll and his friend made a minute investigation of every article

contained therein. Their search was well-nigh fruitless. The trunk

contained little save the wardrobe of a well-dressed man--suits, shirts,

underwear, shoes, caps. There were also golf and tennis togs; a few

books; a handsome leather secretary, containing a good many personal

letters and one or two business missives which were of little interest.

Altogether the examination of the trunk--a process which occupied three

hours--established nothing definite, save that there was nothing to be

discovered. Its results were hopelessly negative.

Meanwhile the city sizzled with gossip of the Warren murder. The

seemingly impenetrable mystery surrounding the case, its many sensational

features, the admission of the police department that the woman in the

case was not Hazel Gresham, fiancée of the dead man, yet the certainty

that there was a woman, and that she was of the better class--all this

served to keep the tongues of men and women alike wagging at both ends.

Carroll was besieged with anonymous letters. Dozens of prominent

married women were mentioned as having been, at one time or another,

the object of Warren's amorous attentions. Carroll read each one

carefully and filed it away. He had hoped for this, but the results had

far exceeded his expectations, and he found himself bewildered rather

than assisted by the response from nameless individuals who were

morbidly eager to be of help.

The detective knew that the running down of each individual trail--the

investigation of each of Warren's supposed affairs of the heart--would be

an interminable procedure. And so far not a single one of the letters had

varied from another. They connected Warren's name with that of some

married woman, and let it go at that. It was quite evident that the dead

man had been very much of a Lothario; too much so for the mental ease of

the investigator who was struggling to link the cause of his death with

one particular affair.

The reporters allowed their imaginations to run wild. The story was what

is known, in the parlance of the newspaper world, as a "space-eater."

City editors turned their best men loose on it and devoted columns to

conjecture. There was little definite information upon which to base the

daily stories that were luridly hurled into type. Thus far Spike Walters,

driver of taxicab No. 92,381, was the only person under arrest, and only

those persons too lazy to exercise their minds were willing to believe

that Spike was guilty or that he knew more of the crime than he had told.

Carroll read each news story attentively. No wild theory of a pop-eyed

reporter, hungry for fact, was too absurd to receive his careful

attention. But they proved of little assistance. With the spot-light of

publicity blazing on the crime, the investigation seemed to have become

static. There was no forward movement; nothing save that in the brain of

David Carroll salient facts were being seized upon and meticulously

catalogued for future reference.

Cartwright and Reed, the plain-clothes men detailed to shadow William

Barker, reported nothing suspicious in that gentleman's movements. He

seemed to be making no effort to secure employment, but, on the other

hand, there was little of interest in what he did do. Again the stone

wall of negative action.

Barker spent his mornings in his boarding-house, apparently luxuriating

in long slumbers; he ate always at the same cheap restaurant; and his

afternoons and evenings were devoted largely to the science of eight-ball

pool at Kelly's place. There may have been significance in his loyalty to

Kelly's place; but if there was, it was too vague for Carroll to

consider. He merely remembered the fact that Barker was a steady patron

of the pool-room near the Union Station, and filed it away with his

other threads of information concerning the murder.

Carroll was frankly puzzled. The case differed widely from any other

with which he had ever come in contact. Usually there was an array of

persons upon whom suspicion could be justly thrown; a collection of

suspects from whom the investigator could take his choice, or from whom

he could extract facts which eventually might be used to corner the

guilty person. In the present case there was no one to whom he could

turn an accusing finger.

Of course, he was convinced that William Barker knew a great deal about

the crime and the events which preceded it; but Barker wouldn't talk--and

he, Carroll, had no evidence that enabled him to bluff, to draw Barker

out against his will.

The crime seemed to have lost itself in the sleety cold of the December

midnight upon which it was committed. The trails were not blind--there

were simply no trails. The circumstances baffled explanation--a lone

woman entering an empty taxicab; a run to a distant point in the city;

the discovery of the woman's disappearance, and in her stead the sight of

the dead body of a prominent society man--that, and the further blind

information that the suit-case which the woman had carried was the

property of the man whose body was huddled horribly in the taxicab.

The woman, whoever she was, had either been unusually clever or

unusually lucky. Minute examination of the interior of the cab had

revealed nothing--not a fingerprint, nor a scrap of handkerchief.

There was absolutely nothing which could serve as a clue in establishing

her identity.

And yet, somewhere in the city--a city of two hundred thousand souls--was

the woman who could clear up the mystery.

Convinced that she was prominent socially, Carroll kept a close eye upon

the departures of society women for other cities. His vigil had been

unrewarded thus far. And the public as a whole waited eagerly for her

apprehension, for the public was unanimous in the belief that the woman

in the taxicab was the person who had ended Warren's life.

The very fact of having nothing definite upon which to work was getting

on Carroll's usually equable nerves. He had little to say to Leverage

regarding the case, for the simple reason that there was very little

which could be said. Leverage, on his part, watched the detective with

keen interest, sympathizing with him, and exhibiting implicit confidence,

but the men didn't agree upon the correct procedure. Leverage was all for

arresting Barker and charging him with the murder.

"You'll learn some facts then, Carroll," he insisted.

But Carroll shook his head.

"It wouldn't get us anywhere, Eric. We couldn't prove him guilty."

"No-o, but that don't make no difference. Of course the law says a man is

innocent until you prove he ain't, but that ain't what the law does. If

we arrest this here Mr. William Barker, everybody's going to believe he's

guilty until he proves himself innocent."

"And you think he can't do that?"

"No! At least I'm gambling on this--Barker can't prove himself innocent

without telling who is guilty!"

But Carroll refused to arrest the man. He knew that Leverage disapproved,

but he also knew that Leverage was sportsman enough to let him handle the

case in his own way.

On one of his long strolls through the downtown section of the

city--daily walks which helped him to think connectedly--David Carroll

felt a hand on his arm and heard an eager feminine voice in his ear:

"Gracious goodness! If it isn't the perfectly marvelous Mr. David

Carroll!"

Carroll bowed instinctively. Then his lips expanded into the first

wholesome smile he had experienced in forty-eight hours.

"Miss Evelyn Rogers!"

"You did recognize me, didn't you? How simply splendiferous! I'm awfully

glad we met!"

"So am I, Miss Rogers."

She dropped her voice confidentially.

"Will you do me a _great_ favor--an _enormous_ favor?"

"Certainly. What is it?"

"It's this." She looked around carefully. "I told some of my friends that

you are a friend of mine, and they don't believe it. They're over yonder

in that ice-cream place. Now, what I want you to do for me is to show

'em. I want you to take me over there and buy me an ice-cream soda!"

Carroll laughed aloud as he took her by the arm and piloted her through

the traffic. He asked only one question:

"What flavor?"
