waited; and for a whole minute there was silence in the room.
“You have nothing more to say, Captain?” he asked at length; “—no further explanations to give me?”
Leacock did not answer. He sat gazing imperturbably ahead of him; and it was evident he had sealed his lips for the time being.
Markham rose.
“In that case, let us consider the interview at an end.”
The moment Captain Leacock had gone, Markham rang for one of his clerks.
“Tell Ben to have that man followed. Find out where he goes and what he does. I want a report at the Stuyvesant Club to-night.”
When we were alone Vance gave Markham a look of half-bantering admiration.
“Ingenious—not to say artful. . . . But, y’ know, your questions about the lady were shocking bad form.”
“No doubt,” Markham agreed. “But it looks now as if we were on the right track. Leacock didn’t create an impression of unassailable innocence.”
“Didn’t he?” asked Vance. “Just what were the signs of his assailable guilt?”
“You saw him turn white when I questioned him about the weapon. His nerves were on edge,—he was genuinely frightened.”
Vance sighed.
“What a perfect ready-made set of notions you have, Markham! Don’t you know that an innocent man, when he comes under suspicion, is apt to be more nervous than a guilty one, who, to begin with, had enough nerve to commit the crime, and, secondly, realizes that any show of nervousness is regarded as guilt by you lawyer chaps? ‘My strength is as the strength of ten because my heart is pure’ is a mere Sunday-school pleasantry. Touch almost any innocent man on the shoulder and say ‘You’re arrested’, and his pupils will dilate, he’ll break out in a cold sweat, the blood will rush from his face, and he’ll have tremors and dyspnœa. If he’s a hystérique, or a cardiac neurotic, he’ll probably collapse completely. It’s the guilty person who, when thus accosted, lifts his eyebrows in bored surprise and says, ‘You don’t mean it, really,—here have a cigar’.”
“The hardened criminal may act as you say,” Markham conceded; “but an honest man who’s innocent doesn’t go to pieces, even when accused.”
Vance shook his head hopelessly.
“My dear fellow, Crile and Voronoff might have lived in vain for all of you. Manifestations of fear are the result of glandular secretions—nothing more. All they prove is that the person’s thyroid is undeveloped or that his adrenals are subnormal. A man accused of a crime, or shown the bloody weapon with which it was committed, will either smile serenely, or scream, or have hysterics, or faint, or appear disint’rested—according to his hormones, and irrespective of his guilt. Your theory, d’ ye see, would be quite all right if everyone had the same amount of the various internal secretions. But they haven’t. . . . Really, y’ know, you shouldn’t send a man to the electric chair simply because he’s deficient in endocrines. It isn’t cricket.”
Before Markham could reply Swacker appeared at the door and said Heath had arrived.
The Sergeant, beaming with satisfaction, fairly burst into the room. For once he forgot to shake hands.
“Well, it looks like we’d got hold of something workable. I went to this Captain Leacock’s apartment-house last night, and here’s the straight of it:—Leacock was at home the night of the thirteenth all right; but shortly after midnight he went out, headed west—get that!—and he didn’t return till about quarter of one!”
“What about the hall-boy’s original story?” asked Markham.
“That’s the best part of it. Leacock had the boy fixed. Gave him money to swear he hadn’t left the house that night.—What do you think of that, Mr. Markham? Pretty crude—huh? . . . The kid loosened up when I told him I was thinking of sending him up the river for doing the job himself.” Heath laughed unpleasantly. “And he won’t spill anything to Leacock, either.”
Markham nodded his head slowly.
“What you tell me, Sergeant, bears out certain conclusions I arrived at when I talked to Captain Leacock this morning. Ben put a man on him when he left here, and I’m to get a report to-night. To-morrow may see this thing through. I’ll get in touch with you in the morning, and if anything’s to be done, you understand, you’ll have the handling of it.”
When Heath had left us, Markham folded his hands behind his head and leaned back contentedly.
“I think I’ve got the answer,” he said. “The girl dined with Benson and returned to his house afterward. The Captain, suspecting the fact, went out found her there, and shot Benson. That would account not only for her gloves and hand-bag, but for the hour it took her to go from the Marseilles to her home. It would also account for her attitude here Saturday, and for the Captain’s lying about the gun. . . . There, I believe, I have my case. The smashing of the Captain’s alibi about clinches it.”
“Oh, quite,” said Vance airily. “ ‘Hope springs exulting on triumphant wing’.”
Markham regarded him a moment.
“Have you entirely forsworn human reason as a means of reaching a decision? Here we have an admitted threat, a motive, the time, the place, the opportunity, the conduct, and the criminal agent.”
“Those words sound strangely familiar,” smiled Vance. “Didn’t most of ’em fit the young lady also? . . . And you really haven’t got the criminal agent, y’ know. But it’s no doubt floating about the city somewhere.—A mere detail, however.”
“I may not have it in my hand,” Markham countered. “But with a good man on watch every minute, Leacock won’t find much opportunity of disposing of the weapon.”
Vance shrugged indifferently.
“In any event, go easy,” he admonished. “My humble opinion is that you’ve merely unearthed a conspiracy.”
“Conspiracy? . . . Good Lord! What kind?”
“A conspiracy of circumst’nces, don’t y’ know.”
“I’m glad, at any rate, it hasn’t to do with international politics,” returned Markham good-naturedly.
He glanced at the clock.
“You won’t mind if I get to work? I’ve a dozen things to attend to, and a couple of committees to see. . . . Why don’t you go across the hall and have a talk with Ben Hanlon, and then come back at twelve-thirty? We’ll have lunch together at the Bankers’ Club. Ben’s our greatest expert on foreign extradition, and has spent most of his life chasing about the world after fugitives from justice. He’ll spin you some good yarns.”
“How perfectly fascinatin’!” exclaimed Vance, with a yawn.
But instead of taking the suggestion, he walked to the window and lit a cigarette. He stood for a while puffing at it, rolling it between his fingers, and inspecting it critically.
“Y’ know, Markham,” he observed,
