His voice full of excitement, he said, "get the constables stationed round the house, right out of the way. Put them and the other men where they won't be able to see or hear what goes on at the back. Then make some excuse of having to examine the body in reference to new evidence that I have brought back with me. I'll join you there in half an hour."

Mr. Narkom gave a nod of comprehension and vanished up the path where his men had been stationed, leaving Cleek to carry out his plans.

Thirty minutes later, with his customary soundlessness, he came up out of the gloom of the neglected gardens and entered Cheyne Court, joining the Superintendent in the ballroom, where in a hastily constructed coffin lay the body of the stranger—a stranger no longer to Cleek.

He stood with frowning brows and regarded the dead man steadily.

"So it was a failure after all, Blake," he said, softly. "After escaping the price all these years, to be caught like a rat in a trap for the sake of a purple stone! Well! life is a queer mixture at best. But you've drunk your glass to the dregs, Blake, and it owes nothing at least to you!"

"Blake," ejaculated Mr. Narkom, "do you mean to say that you have found out—that this—no, no—surely not—not James Blake—the head of the Pentacle gang? The greatest set of rogues that ever saw their names in the calendar. Not that Blake, Cleek?"

Cleek smiled.

"The very same," he responded, gravely. "Give me but a few hours now, and I will put the whole gang into your hands, but now there's something I want to finish up here. I didn't want to do it this morning, and I don't know but what we are too late now. Try and find the very centre of this room for me, there's a good fellow, and stand there while I do a little measuring and counting."

Mr. Narkom took out his torch and sent it sweeping round the great room, until he found what he took to be the exact centre and announced the fact.

"Good!" said Cleek. "We'll make sure to save time. Now, let's see; here is one piece of wood. Now for the five others."
