"The valet was about to shut the door, saying that Mr. Depping could see no one, when the man put his foot in die door. He said" — Hadley glanced at his notes—"he said, 'Hell see me. Ask him.' Inspector Murch was not very clear about this. The man seems to have pointed to some sort of speaking tube."

"Right" said the colonel. "You know. You whistle in 'em, demmit. Then you talk. Depping only used two rooms to live in: study and bedroom. He'd got a speaking tube running up to the study. It was beside the outer door."

"Very well… The man was insistent, so Storer spoke to Mr. Depping upstairs. Mr. Depping finally said, 'All right; send him up,' though the man would give no name. But Depping told the valet to be close at hand, in case he should be needed. Storer suggested that he had better go and see to fixing the lights, whereupon Depping said not to mind the lights; that he had plenty of candles in the study, and they would suffice.

"However, Storer woke up the cook, a man named Achille Georges, and sent him out in the rain with a flashlight — under great protest — to find out whether or not the wires had come down. Meantime he was going about shutting the upstairs windows, and he heard Depping and his guest talking in the study. He couldn't hear anything that was said, but they seemed on amiable enough terms. Presently the cook returned, swearing no wire was down. They had a look at the fuse box, and discovered that there had only been a short circuit of some sort, and that plugging in new fuses restored the lights… "

For the first time Dr. Fell, who had been sitting abstractedly filling a pipe, rolled up his big head and stared at the chief inspector. His eyes had a curiously cross-eyed look. A long sniff rumbled in his nose.

"I say, Hadley," he muttered, "that's very interesting; It's the first interesting detail you've mentioned so far. Go on, go on."

Hadley grunted. He looked speculatively at the doctor, and went on:

"By that time it was nearly midnight, and Storer wanted to get to bed. He knocked on the study door, told Depping the lights were repaired, and asked whether he could retire. Depping said, 'Yes, yes,' rather impatiently. So he turned in. There was still a terrific thunderstorm going on, and it kept him awake… On reflection, this morning, he thinks he heard the sound of a shot about a quarter past twelve; he noticed it at the time, but he thought it must be a part of a thunderclap, and didn't investigate. Inspector Murch says the police surgeon reports a quarter past twelve to be about the time of death.

"The next morning, when Storer went downstairs, he saw over the transom that the lights were still burning in the study. He knocked at the door for some time, and got no answer; the door was locked on the inside. So he got a chair, climbed up, and looked through the transom.

"Depping was lying forward across his reading desk, with the back of his head shot open direcdy against the bald spot. Finally Storer plucked up enough nerve to push the transom back, crawl through, and get into the room. Depping had been dead for many hours, and there was no weapon to be found."
