"No. He tried to have me arrested, and failed. I think he looked on me as an unlikely subject to yield unnecessary information."

"Supper is served, sir," said a maître d'hôtel to Uncle Horace, and further discussion of Count Vassilan's tangled matrimonial schemes became difficult for the moment.

Steingall was pressed to join the party—without prejudice to any official duties he might be called on to perform next day, as Curtis put it pleasantly—and consented. Once again had his instinct been justified, for he was sure that Lady Hermione's Parisian reminiscences would prove important in some way not yet determinable. Moreover, his colleagues knew he was at the Plaza Hotel, and he was content to remain there while his trusted aide, Clancy, was acting as chauffeur during Count Vassilan's belated excursion.

The police captain was keeping an eye on the Waldorf-Astoria, a detective was searching the apartment rented by the murdered journalist, and other men of the Bureau were hunting the record of the automobile, though Steingall was convinced that this branch of the inquiry would end in a blind alley, because the car had undoubtedly been stolen, and its lawful owner would only be able to identify it, and declare that, to the best of his belief, it was locked in a garage at the time it was being used for the commission of a crime. Steingall assumed that the unfortunate Hunter—or it might have been de Courtois—was led to hire this particular vehicle by adroit misrepresentation on the part of some unknown scoundrels who were aware of the contemplated marriage. The shorthand notes in Hunter's book bore out this theory, because they were obviously data supplied by de Courtois which would have enabled the journalist to write a thoroughly sensational story next day. He was convinced, when the truth was known, it would be discovered that Hunter made the Frenchman's acquaintance owing to his habit of mixing with the strange underworld from the Continent of Europe which has its lost legion in New York. De Courtois was just the sort of vainglorious little man who would welcome the notoriety of such an adventure as the prevented marriage ceremony, wherein his name would figure with those of distinguished people, and the last thing he counted on was the murder of the scribe who had promised him columns of descriptive matter in the press. The pert musician was not the first, nor would he be the last, to find that the role of cat's-paw is apt to prove more exacting than was anticipated. To his chagrin, he saw himself changed suddenly from a trusted agent into a dupe, and his utter collapse on hearing of the murder fitted in exactly with the theory taking shape in the detective's mind—that there were two implacable forces at war in New York that night, that Lady Hermione's marriage to Count Vassilan or the Frenchman provided the immediate bone of contention, and that the struggle had been complicated by a too literal interpretation of instructions carried out by bitter partisans.

In the midst of a lively conversation, the telephone jangled its imperative message from a wall bracket in the room. Devar was nearest the instrument, and he answered the call.

"It's for you, Mr. Steingall," he said.

The detective would have preferred greater privacy, but he rose at once and answered.

"And who is Mr. Krantz?" he demanded. Then, after a pause: "Oh, yes.… Is he?… You needn't trouble at all about that. The police surgeon, at my request, has dosed him with sufficient bromide to keep him quiet till to-morrow morning.… Yes, I understand. Tell them it can't be done, and refer them to the Centre-street Bureau.… What?… No, so far as I can guess, the engineer won't be wanted again to-night."

He hung up the receiver, and returned to his seat, though he had just been informed that the Earl of Valletort and another person, having ascertained by some means that de Courtois still lived, were raising a commotion at the Central Hotel and demanding access to the Frenchman's room.
