she realised what liberties she was taking in the master's house, she had led him into a small sitting room at the end of a short passage leading out of the hall. It had evidently been intended for a smoking room or study when the villa was built, but was clearly never used by Mr. Rattar, for it contained little furniture beyond bookcases.

"Yes," said the visitor thoughtfully, "they seem to have been made by a tacketty boot."
"And forbye that, there was a wee bit mud on the floor and a tacket mark in that!"
"Was the window shut or open?"
"Shut, sir; and the most extraordinary thing was that it was snibbed too! That's what made the master say it couldna have been a burglar at all, or how did he snib the window after he went out again?"
