“And I saw Burr junior open the big bin where he and Mercer keep their rubbish.”

“It may not be rubbish to them,” said the Doctor, “Go on, sir.”

“And after fiddling about a bit, and looking round to see if he was watched, Burr junior took up a stuffed rabbit, put his hand inside, and pulled out some tow, and then he opened that, and took out Burr major’s silver watch.”

“How do you know it was?” said the Doctor sharply.

“Because we saw it such lots of times, sir, and I knew it again directly.”

“It might have been any watch,” said the Doctor. “Go on.”

“Yes, sir. And he looked at it, and played with it ever so long, and then wrapped it up in tow again, and stuffed it inside the rabbit, and then locked up the bin, put the key in his pocket, and went down.”

“And you?”

“I waited till he had gone, sir, and then I ran and told Burr major, sir.”
