"Well, I think it was old Twells," he said. "He's a bit of a character, kind of naturalist and all that sort of thing," Bristol stammered. "He said Wills, the butler, had told him on his way to Doctor Smith's, and as I passed him ... he told me.

"Passed him!" ejaculated Cleek. "Where were you; where had you been during the evening?"

"Most of the time, at the Electric Power House. I know one of the engineers there, and I just happened to be there, and so ... so...." His voice trailed away as though he had given the most lucid of explanations.

"I see," said Cleek, pinching up his chin, as the thoughts raced through his mind. What connection had this explanation with the sudden failure of the electric light at the exact moment of the discovery of the murder, and how was Miss Parradine connected with it? Were the two in league, after all? But he said no more, only switched round on his heel and allowed himself to be led upstairs to the gallery where the dead man still lay.

It was a large square room, solidly built, without corners or panels. Along its dull, gray-papered walls hung large pictures of long dead and gone ancestors of the owner of Manor Lodge, himself a wanderer in strange lands. Small tables held the cases of curios collected by Anthony Winton, and but one big window gave it light. Clearly there was no room for concealment of any unknown assailant, and when Cleek had dismissed the plain-clothes man on guard, and told Calvert, who had quickly been sent for at Cleek's request, to open up the blind, he turned his attention to the dead man.

As Mr. Narkom had said, there was no sign of wound or mark on the body.

"Suffocated, it is clear enough," commented Cleek, having made minute examination. "But how?" He looked round. "You have no gas fittings here?"

"None in the house, sir," said Calvert. "The whole place was lit by oil-lamps till my master took it and then the local company wired it for electricity. All the rooms are not done yet, but this one and downstairs were finished first. The company also connected up the house telephone to theirs, so as to oblige Mr. Winton while waiting for his own connection with the company. I suppose that was why that went wrong, too, when the electric light went off."

"What did he have to eat last?" said Cleek, suddenly, almost as if he had not been listening. "Do you know?"
