"I know better than that. A personal acquaintance of mine, this quarry is. Almost a relation, one might say." He expelled his breath in a whispered laugh. "A sheer drop to the ground, half a hillside away."

Brat wondered if he had time to slide down the rope in one swift rush before Simon cut it. The footholds had been for coming up again. He could just ignore them and slide. Would he be near enough the bottom before Simon realised what he had done?

Or would it be better — ? Yes. His hand tightened on the rope and he pressed on his toe-hold and lifted himself until he had almost got one knee on the turf again. But Simon must have his hand on the rope somewhere. He had felt the movement.

"Oh, no, you don't!" he said, and brought his heel down on Brat's hand. Brat grabbed the foot with his other hand and hung on, his fingers in the opening of the shoe. Simon brought his knife down on Brat's wrist and Brat yelled, but continued to hang on. He dragged his right hand from under Simon's shoe and caught him round the back of the ankle. He was covering with his body the rope in front of Simon and as long as he held on Simon could not turn to cut the rope behind him. It is very upsetting to have one's foot grasped from below when one is standing on the very edge of a precipice.

"Let go!" said Simon, stabbing frantically.

"If you don't stop that," panted Brat, "I'll drag you over with me."

"Let go! Let go!" Simon said, hitting wildly in blind panic and not listening.

Brat removed the hand that was holding on to the edge of the shoe and caught the knife-hand as it came down. He now had his right hand round Simon's left ankle, and his left hand was clutching Simon's right wrist.

Simon screamed and pulled away, but Brat hung his weight on the wrist. He had the confidence of a toe-hold, but Simon had nothing to brace himself against. Simon tore at the hand that was hanging on to his knife-wrist, and Brat, with a great heave, took his right hand from Simon's foot and caught Simon's left hand with it. He had now got Simon by both wrists, and Simon was bent over like a bow above him.

"Drop that knife!" he said.
