"The hospital is crowded with patients, and here you immobilize me for half a morning. I can't pretend to set a compound fracture in ten minutes, you know! Why couldn't you break your neck and have me sign a death certificate?"

"Didn't occur to me," said Grim. "But never mind, doc. You need a rest. Here's tobacco, lots to read, and an armchair. Lock yourself in and be happy."

"Who's this?" asked Templeton, looking down at me.

"Deaf and dumb poor devil, earning a few piastres by working for the Intelligence."

"Spy, eh? He looks fit for honest work if he had all his faculties. Is he dumb as well as deaf, or because he's deaf?"

"Dunno," said Grim. "He never speaks."

"Perhaps I can do something for him. Suppose you leave him here with me. I can give him a thorough examination instead of wasting my time here."

"He's got a job of work to do right now," said Grim.

"Does he know the sign language? Have you any way of telling him to come and see me at the hospital?"

"I give him written instructions in Arabic."
