Devar was beginning to enjoy himself. He alone was able to estimate Curtis at his true worth; even that astounding marriage was losing some of its bizarre attributes since Curtis had begun to talk about it.

"Good for you, Mr. Curtis, senior," he crowed delightedly. "If Indiana knew what it really wanted it would run you for Governor."

Steingall nearly became angry. Indeed, it is probable that he would have expressed his sentiments in strong language were it not for the presence of Mrs. Curtis.

"Now, sir," he said, with a perceptible stiffening of manner, "let us have done with pretense. You strike me as being sane, yet you ask me to believe that you have acted like a lunatic. Well, let it go at that. Who is this Jean de Courtois, whom Lady Hermione Grandison was to have married to-night?"

"My wife tells me that he is a French music-master whom she hired to marry her in order that she might escape from a pestiferous person named Count Ladislas Vassilan," replied Curtis with cool directness. "She brought the obliging individual with her from Paris for the purpose, and paid him a thousand dollars as a sort of retaining fee. From what little I have seen of her, she impresses me as a charming girl wholly without experience of a world which, though not altogether wicked, is nevertheless callous and self-seeking. Among other drawbacks, she embarked on a fantastic project with a most disingenuous belief in the good faith of a Frenchman. Now, I admire France as a nation, but where women are concerned, I distrust Frenchmen as a race, and I suspect—mind you, I am merely guessing—but I repeat that I suspect the honesty of Monsieur Jean de Courtois in this matter. There was no earthly reason why he should not have married Lady Hermione some weeks ago, but it is clear that he has used every artifice to delay the ceremony until to-night—and, it may be found when we learn the facts, was prepared to put it off once more till to-morrow or next day. Why? In my opinion, the reason is not far to seek. The Earl of Valletort and Count Ladislas Vassilan were crossing the Atlantic hot in pursuit of the unwilling bride. They arrived in New York to-night, and were so well posted in events, both past and prospective, that they headed straight for the flat in which Lady Hermione was living with her maid. Naturally, I am keenly interested in the causes which led up to a peculiarly brutal and uncalled-for murder, and, as my wife's husband, I have the further incentive of hoping to bring to justice certain of her persecutors whom I cannot help connecting indirectly with the crime of which I was, I suppose, one of the most credible and intelligent witnesses. Now, before I was aware that such a winsome creature existed as the present Lady Hermione Curtis, I had estimated the murderers as Hungarians, two of them at any rate, since I am hardly prepared to vouch for the chauffeur. Count Ladislas Vassilan is a Hungarian. The poor fellow who was killed, though his name is American enough, spoke French with a pure accent. One of the Hungarians spoke French, fluently but vilely. Jean de Courtois is admittedly a Frenchman. I am not a detective, Mr. Steingall, but as a plain man of affairs I am forced to the conclusion that there has seldom been a similarly mysterious crime in which certain lines of inquiry thrust themselves more pertinently on the imagination. To sum up, I advise you to find Jean de Courtois—unless, indeed, he, too, has been killed—and you will be in close touch with the origin of the whole ugly business."

"Good egg!" cried the irresistible Devar. "It's a pity you were not with us on the Lusitania, Mr. Steingall, or you would realize that when John D. rears up on his hind legs, and talks like that, there is nothing more to be said."

"Is Lady Hermione a pretty girl?" demanded Mrs. Curtis eagerly. Her democratic soul was rejoicing in the discovery that her nephew's wife did not lose her title because of the marriage. Of course, no one ever before heard of such folly as this matrimonial leap in the dark, but, once taken, there was satisfaction in the thought that the bride was an earl's daughter. Moreover, she had read of such queer goings on among the British Aristocracy that a wedding at sight was a comparatively venial offense.

Curtis assured his aunt that Hermione was the most beautiful and fascinating person he had ever met, and Steingall listened to the eulogy with a grinning rictus of jaw. In the whole course of his professional experience he had never encountered anything on a par with this capricious blend of comedy and tragedy.

Of course, it did not escape his acute brain that Curtis was right in assuming that the clou of the situation lay with Jean de Courtois. Dead or alive, the Frenchman must be found, and found quickly. The extraordinary story told by Curtis, if true—and the detective was persuaded that this curiously constituted young man was not trying to hoodwink him in any particular—pointed a ready way toward investigation. The unfortunate journalist, Hunter, was about to enter the Central Hotel when he was attacked so mercilessly. As a consequence, some knowledge of de Courtois was probably awaiting the first questioner at the inquiry counter. What a whimsical incongruity it would be if he were told that the French music-master around whom the inquiry pivoted was within arm's length all the time! He had actually turned to the door in order to summon the hotel clerk when that worthy himself knocked and entered.

"The Earl of Valletort is here, and wishes to have a word with you, Mr. Steingall," he said.
