"Sir Horace always locked his desk?"

"Yes, sir."

"None of your keys will open it, of course?"

"No, sir. That is--I don't know, sir. I've never tried."

Inspector Chippenfield grunted slightly. That trap the butler had not
seen until too late. But of course all servants went through their
masters' private papers when they got the chance.

"Do you know if Sir Horace was in the habit of carrying a
pocket-book?" he asked.

"Yes, sir; he was."

"What sort of a pocket-book?"

"A large Russian leather one with a gold clasp."

"Did he take it away with him when he went to Scotland? Did you see it
about the house after he left?"

"No, sir. I think he took it with him. It would not be like him to forget
it, or to leave it lying about."

"And what sort of a man was Sir Horace, Field?"
