Clayton naturally had bowed to look for it, whereupon the rascal instantly threw one arm around his head, covering his mouth, and at the same moment thrust the needle of a hypodermic syringe into his neck, injecting a quantity of the same potent and quick-acting drug with which, Nick immediately suspected, Clayton had been overcome by Margate at the time of his escape after the jewel robbery.

Clayton knew nothing of what had followed, having quickly lost consciousness, and Nick now left Mr. Langham and the physicians to enlighten him with the sad information. He withdrew with Patsy and hastened down to the private library in which he had been talking with Langham only a few minutes before.

Patsy already had told him about finding the waiter, Toulon, and Nick’s next move was to send for Mrs. Julia Clayton, whom he briefly informed of his suspicions, and then cautioned the dismayed woman against inadvertently betraying the secret she so long had kept from all the world.[Pg 12]

The shocking news now was generally known, and the house was in confusion. Guests were hurriedly departing, leaving sympathetic messages with the butler and other servants. All keenly felt that they could be of no assistance in the investigations then in progress, and that they were better out of the way.

“Gee whiz! there’s nothing to this, chief,” commented Patsy, turning after closing the door upon Mrs. Clayton. “This is Margate’s doings, all right.”

“Undoubtedly,” said Nick. “He served Clayton the same trick as before.”

“Surest thing you know.”

“We will try later to find out how he got away with the girl. It would be useless to undertake it at present, and immediate pursuit is out of the question. A hundred conveyances have left here during the past half hour.”

“I guess you are right, chief,” Patsy agreed.

“I know that I am,” Nick replied. “We may, however, accomplish something of importance. Margate is a past master of the art of making up and impersonating others. It seems very evident that he impersonated the waiter Toulon, but whether with Toulon’s consent and assistance, or whether he is an innocent victim of the rascal, is an open question.”
