Harold produced pencil and paper, and the Professor proceeded to give an account of how he had spent the afternoon. After some delay the authorities at Scotland Yard, who were always anxious to carry out any of Dr. Priestley’s requests, even though they were ignorant of the motive behind them, had found the record of Morlandson’s career after his sentence. He had been sent to Dartmoor, and had served his time there. He had been released on licence in 1920, having undergone fourteen years of his sentence. He had then remained for a short time in London, arranging his affairs, but had not communicated with anybody but his solicitor, to whom he had expressed his intention of spending the rest of his life in the most complete seclusion, and devoting himself to chemical research, for which he had always had a bent during the period in which he was in practice.
