She had not blood enough to sin.”
Years of repression had told upon her, and she looked older than she really was—so old and so dragged out, in fact, that Mrs. Armroyd, the cook, appeared youthful and attractive in contrast. Indeed, it was no wonder that Mr. Ephraim Nippers had been attracted by that good soul; for, although her hair was streaked with gray, and her figure was of the “sack of flour” order, and her eyes were assisted in their offices by a pair of steel-bowed spectacles, her face was still youthful in contour, and Mr. Narkom, looking at her, concluded that at twenty-four or twenty-five she must have been a remarkably pretty and remarkably fascinating woman. What Cleek’s thoughts were upon that subject it is impossible to record; for he merely gave her one look on coming into the room, and then took no further notice of her whatsoever.
“Indeed, Mr. Headland, I am glad—I am very, very glad—that fortune has sent you into this neighbourhood at this terrible time,” said Miss Renfrew when Cleek was introduced. “I do not wish to say anything disparaging of Mr. Nippers, but you can see for yourself how unfitted such men as he and his assistant are to handle an affair of this importance. Indeed, I cannot rid my mind of the thought that if more competent police were on duty here the murder would not have happened. In short, that the assassin, whoever he maybe, counted upon the blundering methods of these men as his passport to safety.”
“My own thought precisely,” said Cleek. “Mr. Nippers has given me a brief outline of the affair—would you mind giving me the full details, Miss Renfrew? At what hour did Mr. Nosworth go into his laboratory? Or don’t you know, exactly?”
“Yes, I know to the fraction of a moment, Mr. Headland. I was looking at my watch at the time. It was exactly eight minutes past seven. We had been going over the monthly accounts together, when he suddenly got up, and without a word walked through that door over there. It leads to a covered passage connecting the house proper with the laboratory. That, as you may have heard, is a circular building with a castellated top. It was built wholly and solely for the carrying on of his experiments. There is but one floor and one window—a very small one about six feet from the ground, and on the side of the Round House which looks away from this building. Nothing but the door to that is on this side, light being supplied to the interior by a roof made entirely of heavy corrugated glass.”
“I see. Then the place is like a huge tube.”
“Exactly—and lined entirely with chilled steel. Such few wooden appliances as are necessary for the equipment of the place are thickly coated with asbestos. I made no comment when my uncle rose and walked in there without a word. I never did. For the past six or seven months he had been absorbed in working out the details of a new invention; and I had become used to his jumping up like that and leaving me. We never have supper in this house—my uncle always called it a useless extravagance. Instead, we defer tea until six o’clock and make that the final meal of the day. It was exactly five minutes to seven when I finished my accounts, and as I had had a hard day of it, I decided to go to bed early, after having first taken a walk as far as the old bridge where I hoped that somebody would be waiting for me.”
“I know,” said Cleek, gently. “I have heard the story. It would be Mr. Charles Drummond, would it not?”
“Yes. He was not there, however. Something must have prevented his coming.”
“Hum-m-m! Go on, please.”
