Ten minutes later, just on the stroke of eleven, Ryland stalked up, his hat over his eyes and the inevitable cigar in his mouth. He gave a quick look round, and then plunged into the hollows of the quarry below. Presently I heard a low murmur of voices come up to me. Evidently the other man⁠—or men⁠—whoever they were, had arrived first at the rendezvous. I crawled cautiously out of the bushes, and inch by inch, using the utmost precaution against noise, I wormed myself down the steep path. Only a boulder now separated me from the talking men. Secure in the blackness, I peeped round the edge of it and found myself facing the muzzle of a black, murderous-looking automatic!

“Hands up!” said Mr. Ryland succinctly. “I’ve been waiting for you.”

He was seated in the shadow of the rock, so that I could not see his face, but the menace in his voice was unpleasant. Then I felt a ring of cold steel on the back of my neck, and Ryland lowered his own automatic.
