When Farrow arrived at the head of his legion he was just in time to salute his Inspector, who had cycled from Easton after receiving the news left by the chauffeur at the police station. Farrow was bursting with impatience to reveal the discoveries he had made, though resolved to keep locked in his own breast the secret confided by Bates. He was thoroughly nonplussed, therefore, when Winter, after listening in silence to the account of the footprints and scratches on the moss-covered surface of the rock, turned to Hilton Fenley.

"With reference to the rifle which has been mentioned—where is it kept?" he said.

"In my brother's room. He bought it nearly a year ago, when he was planning an expedition to Somaliland."

"May I see it?"

Fenley signed to the butler, who was standing with the others at a little distance.

"You know the .450 Express which is in the gun rack in Mr. Robert's den?" he said. "Bring it to the Superintendent."

Tomlinson, shaken but dignified, and rather purple of face as the result of the tramp through the trees, went indoors. Soon he came back, and the rich tint had faded again from his complexion.

"Sorry, sir," he said huskily, "but the rifle is not there."

"Not there!"
