opened it for him! Did Sir Reginald ever sit with his window open late at night at this time of year?"
"Never once, sir," said Bisset confidently. "He likit fresh air outside fine but never kept his windies open much unless the weather was vera propitious."
"Then," said Ned, "why should Sir Reginald have opened the window of his own accord to a stranger at the dead of night?"
"Exactly!" said Mr. Rattar. "Thing seems absurd. He'd never do it."
"That's my own opinion likewise, sir," put in Bisset.
"It's only common sense," added the superintendent.
"Then how came the window to be unfastened?" demanded Ned.
"I've suggested a reason," said Simon.
"As a blind? Sounds to me damned thin."
Simon Rattar turned away from him with an air that suggested that he thought it time to indicate distinctly that he was in charge of the case and not the laird of Stanesland.
"That's all we can do just now, Sutherland," he said. "No use disturbing the household any longer at present."
Cromarty stepped up to him suddenly and asked:
"Tell me honestly! Do you suspect anybody?"
Simon shook his head decidedly.
