A different type of district attorney would no doubt have attempted to use the pressure of his office to force her into a more amenable frame of mind. But Markham shrank instinctively from the bludgeoning, threatening methods of the ordinary Public Prosecutor, especially in his dealings with women. In the present case, however, had it not been for Vance’s strictures at the Club, he would no doubt have taken a more aggressive stand. But it was evident he was laboring under a burden of uncertainty superinduced by Vance’s words and augmented by the evasive deportment of the woman herself.
After a moment’s silence he asked grimly:
“You did considerable speculating through the firm of Benson and Benson, did you not?”
A faint ring of musical laughter greeted this question.
“I see that the dear Major has been telling tales. . . . Yes, I’ve been gambling most extravagantly. And I had no business to do it. I’m afraid I’m avaricious.”
“And is it not true that you’ve lost heavily of late—that, in fact, Mr. Alvin Benson called upon you for additional margin and finally sold out your securities?”
“I wish to Heaven it were not true,” she lamented, with a look of simulated tragedy. Then: “Am I supposed to have done away with Mr. Benson out of sordid revenge, or as an act of just retribution?” She smiled archly and waited expectantly, as if her question had been part of a guessing game.
Markham’s eyes hardened as he coldly enunciated his next words.
“Is it not a fact that Captain Philip Leacock owned just such a pistol as Mr. Benson was killed with—a forty-five army Colt automatic?”
At the mention of her fiancé's name she stiffened perceptibly and caught her breath. The part she had been playing fell from her, and a faint flush suffused her cheeks and extended to her forehead. But almost immediately she had reassumed her rôle of playful indifference.
“I never inquired into the make or calibre of Captain Leacock’s fire-arms,” she returned carelessly.
“And is it not a fact,” pursued Markham’s imperturbable voice, “that Captain Leacock lent you his pistol when he called at your apartment on the morning before the murder?”
“It’s most ungallant of you, Mr. Markham,” she reprimanded him coyly, “to inquire into the personal relations of an engaged couple; for I am betrothed to Captain Leacock—though you probably know it already.”
Markham stood up, controlling himself with effort.
“Am I to understand that you refuse to answer any of my questions, or to endeavor to extricate yourself from the very serious position you are in?”
She appeared to consider.
“Yes,” she said slowly, “I haven’t anything I care especially to say just now.”
Markham leaned over and rested both hands on the desk.
“Do you realize the possible consequences of your attitude?” he asked ominously. “The facts I know regarding your connection with the case, coupled with your refusal to offer a single extenuating explanation, give me more grounds than I actually need to order your being held.”
I was watching her closely as he spoke, and it seemed to me that her eyelids drooped involuntarily the merest fraction of an inch. But she gave no other indication of being affected by the pronouncement, and merely looked at the District Attorney with an air of defiant amusement.
Markham, with a sudden contraction of the jaw, turned and reached toward a bell-button beneath the edge of his desk. But, in doing so, his glance fell upon Vance; and he paused indecisively. The look he had encountered on the other’s face was one of reproachful amazement: not only did it express complete surprise at his apparent decision, but it stated, more eloquently than words could have done, that he was about to commit an act of irreparable folly.
There were several moments of tense silence in the room. Then calmly and unhurriedly Miss St. Clair opened her vanity-case and powdered her nose. When she had finished, she turned a serene gaze upon the District Attorney.
“Well, do you want to arrest me now?” she asked.
Markham regarded her for a moment, deliberating. Instead of answering at once, he went to the window and stood for a full minute looking down upon the Bridge of Sighs which connects the Criminal Courts Building with the Tombs.
“No, I think not to-day,” he said slowly.
He stood a while longer in absorbed contemplation; then, as if shaking off his mood of irresolution, he swung about and confronted the woman.
“I’m not going to arrest you—yet,” he reiterated, a bit harshly. “But I’m going to order you to remain in New York for the present. And if you attempt to leave, you will be arrested. I hope that is clear.”
He pressed a button, and his secretary entered.
“Swacker, please escort Miss St. Clair downstairs, and call a taxicab for her. . . . Then you can go home yourself.”
She rose and gave Markham a little nod.
“You were very kind to lend me my cigarette-holder,” she said pleasantly, laying it on his desk.
Without another word, she walked calmly from the room.
The door had no more than closed behind her when Markham pressed another button. In a few moments the door leading into the outer corridor opened, and a white-haired, middle-aged man appeared.
“Ben,” ordered Markham hurriedly, “have that woman that Swacker’s taking downstairs followed. Keep her under surveillance, and don’t let her get lost. She’s not to leave the city—understand? It’s the St. Clair woman Tracy dug up.”
When the man had gone, Markham turned and stood glowering at Vance.
“What do you think of your innocent young lady now?” he asked, with an air of belligerent triumph.
“Nice gel—eh, what?” replied Vance blandly. “Extr’ordin’ry control. And she’s about to marry a professional milit’ry man! Ah, well. De gustibus. . . . Y’ know, I was afraid for a moment you were actu’lly going to send for the manacles. And if you had, Markham old dear, you’d have regretted it to your dying day.”
Markham studied him for a few seconds. He knew there was something more than a mere whim beneath Vance’s certitude of manner; and it was this knowledge that had stayed his hand when he was about to have the woman placed in custody.
“Her attitude was certainly not conducive to one’s belief in her innocence,” Markham objected. “She played her part damned cleverly, though. But it was just the part a shrewd woman, knowing herself guilty, would have played.”
“I say, didn’t it occur to you,” asked Vance, “that perhaps she didn’t care a farthing whether you thought her guilty or not?—that, in fact, she was a bit disappointed when you let her go?”
“That’s hardly the way I read the situation,” returned Markham. “Whether guilty or innocent, a person doesn’t ordinarily invite arrest.”
“By the bye,” asked Vance, “where was the fortunate swain during the hour of Alvin’s passing?”
“Do you think we didn’t check up on that point?” Markham spoke with disdain. “Captain Leacock was at his own apartment that night from eight o’clock on.”
“Was he, really?” airily retorted Vance. “A most model young fella!”
Again Markham looked at him sharply.
“I’d like to know what weird theory has been struggling in your brain to-day,” he mused. “Now that I’ve let the lady go temporarily—which is what you obviously wanted me to do—, and have stultified my own better judgment in so doing, why not tell me frankly what you’ve got up your sleeve?”
“ ‘Up
