"What time did you go to bed?"

"Ten."

"Then the theft occurred between the hours of ten and seven-thirty. Mind you, I'm giving you a jolly good leg-up, young Pillingshot. But as it's your first case I don't mind. That'll be all from you, Evans. Pop off."

Evans disappeared. Scott turned to the detective.

"Well, young Pillingshot," he said, "what do you make of it?"

"I don't know."

"What steps do you propose to take?"

"I don't know."

"You're a lot of use, aren't you? As a start, you'd better examine the scene of the robbery, I should say."

Pillingshot reluctantly left the room.
