"Then why do you think it was upset?"
"I picked up yon bits of sealing wax and yon piece of India rubber," said Bisset, looking round again. "I know they were on the wee table yesterday and I found them under the curtain in the morning and the table moved over to the wall. It follows that the table has been cowpit and then set up again in another place, and the 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.
