He pressed a buzzer, and ordered a clerk to fill out the necessary requisition. When it had been signed in duplicate, he sent Swacker with it to Ben Hanlon.

“Do ask him about those silk shirts,” suggested Vance. “And find out, if you can, if he considers a white waistcoat de rigueur with a dinner-jacket.”

“This office isn’t a male millinery shop,” snapped Markham.

“But, Markham dear, you won’t learn anything else from this Petronius.”

Ten minutes later a Deputy Sheriff from the Tombs entered with his handcuffed prisoner.

Skeel’s appearance that morning belied his sobriquet of Dude. He was haggard and pale: his ordeal of the previous night had left its imprint upon him. He was unshaven; his hair was uncombed; the ends of his moustache drooped; and his cravat was awry. But despite his bedraggled condition, his manner was jaunty and contemptuous. He gave Heath a defiant leer, and faced the District Attorney with swaggering indifference.

To Markham’s questions he doggedly repeated the same story he had told Heath. He clung tenaciously to every detail of it with the ready accuracy of a man who had painstakingly memorized a lesson and was thoroughly familiar with it. Markham coaxed, threatened, bullied. All hint of his usual affability was gone: he was like an inexorable dynamic machine. But Skeel, whose nerves seemed to be made of iron, withstood the vicious fire of his cross-questioning without wincing; and, I confess, his resistance somewhat aroused my admiration despite my revulsion toward him and all he stood for.

After half an hour Markham gave up, completely baffled in his efforts to elicit any damaging admissions from the man. He was about to dismiss him when Vance rose languidly and strolled to the District Attorney’s desk. Seating himself on the edge of it, he regarded Skeel with impersonal curiosity.

“So you’re a devotee of Khun Khan, eh?” he remarked indifferently. “Silly game, what? More interestin’ than Conquain or Rum, though. Used to be played in the London clubs. Of East Indian origin, I believe. . . . You still play it with two decks, I suppose, and permit round-the-corner mating?”

An involuntary frown gathered on Skeel’s forehead. He was used to violent district attorneys, and familiar with the bludgeoning methods of the police, but here was a type of inquisitor entirely new to him; and it was plain that he was both puzzled and apprehensive. He decided to meet this novel antagonist with a smirk of arrogant amusement.
