He unclasped his right hand and exhibited a sovereign. Scott inspected it.
"Is this the one?" he said.
"Yes," said Pillingshot.
"How do you know?"
"It _is_. I've sifted all the evidence."
"Who had bagged it?"
"I don't want to mention names."
"Oh, all right. As he didn't spend any of it, it doesn't much matter.
Not that it's much catch having a thief roaming at large about the house. Anyhow, what put you on to him? How did you get on the track?
You're a jolly smart kid, young Pillingshot. How did you work it?"
"I have my methods," said Pillingshot with dignity.
"Buck up. I shall have to be going over to school in a second."
"I hardly like to tell you."
"Tell me! Dash it all, I put you on to the case. I'm your employer."
"You won't touch me up if I tell you?"
"I will if you don't."
"But not if I do?"
"No."
"And how about the fee?"
"That's all right. Go on."
"All right then. Well, I thought the whole thing over, and I couldn't make anything out of it at first, because it didn't seem likely that Trent or any of the other fellows in the dormitory had taken it; and then suddenly something Evans told me the day before yesterday made it all clear."
"What was that?"
"He said that the matron had just given him back his quid, which one of the housemaids had found on the floor by his bed. It had dropped out of his pocket that first night."
Scott eyed him fixedly. Pillingshot coyly evaded his gaze.
"That was it, was it?" said Scott.
Pillingshot nodded.
"It was a clue," he said. "I worked on it."
