"Did he get—smashed?"

"A bit."

"Ah. Was he able to account for the—accident?"

"Accidents don't need explaining," he said slowly. "But I didn't say this was an accident. Here, get your eye on that."

He drew a piece of saw-blade from his pocket. It was the piece he had picked up in the mill.

"Guess it's the bit where it's 'collared' by the driving arm."
