"That's the unfortunate thing, sir," said the superintendent. "It seems that Sir Reginald had arranged to sleep in his dressing room as he was going to be sitting up late reading."
"Murderer must have known that," put in Simon.
"Almost looks like it," agreed the superintendent.
"And nobody in the house heard or saw anything?"
"Nobody, sir," said the superintendent.
"That's their statement," added the lawyer in his driest voice.
"Was anybody sitting up late?"
"Nobody admits it," said the lawyer, again very drily.
