other things on it put back. Is that not a fair deduction, sir?"
Ned nodded thoughtfully.
"Seems to me so," he said.
"It seems likely enough," the superintendent also agreed. "And if that's the case there would seem to have been some kind of ongoings near the window."
The Procurator Fiscal still seemed unconvinced.
"Nothing to go on. No proper evidence. It leads nowhere definitely," he said.
"Well now," continued the superintendent, "the question is—how did the murderer get into the room? The door was found locked and the key had been taken away, so whether he had locked it from the inside or the outside we can't tell. There's small chance of finding the key, I doubt, for a key's a thing easy hidden away."
"So he might have come in by the door and then left by the door and locked it after him," said Ned. "Or he might have come in by the window, locked the door and gone out by the window. Or he might have come in by the window and gone out by the door, locking it after him. Those are all the chances, aren't they?"
"Indeed, that seems to be them all," said the superintendent with a note of admiration for this clear exposition that seemed to indicate he was better himself at details than deductions.
"And now what about the window? Was that open or shut or what?"
