“Another of them found out,” he thought, as he set to work to draft his statement to the Magistrate.

He was interrupted by the arrival of Fielding.

He imparted all he knew without reservations. Miss Derek had herself driven in the Mudkul car about an hour ago, she and Miss Quested both in a terrible state. They had gone straight to his bungalow where he happened to be, and there and then he had taken down the charge and arranged for the arrest at the railway station.

“What is the charge, precisely?”

“That he followed her into the cave and made insulting advances. She hit at him with her field-glasses; he pulled at them and the strap broke, and that is how she got away. When we searched him just now, they were in his pocket.”

“Oh no, oh no, no; it’ll be cleared up in five minutes,” he cried again.

“Have a look at them.”

The strap had been newly broken, the eye-piece was jammed. The logic of evidence said “Guilty.”

“Did she say any more?”

“There was an echo that appears to have frightened her. Did you go into those caves?”
