A, SHED HAIRS SHOWING THE NAKED BULB, MAGNIFIED 32 DIAMETERS.

B, HAIRS PLUCKED FROM SCALP, SHOWING THE ADHERENT ROOT-SHEATHS, MAGNIFIED 20 DIAMETERS.

The unfortunate Miriam needed no pressing. In a twinkling she had tweaked out a dozen hairs, which a constable handed across to Thorndyke, by whom they were at once fixed in a paper-clip. A second clip being produced from the box, half a dozen hairs taken from the tress which had been found in the dead woman's hand were fixed in it. Then Thorndyke handed the two clips, together with a lens, to the coroner.

"Remarkable!" exclaimed the latter, "and most conclusive." He passed the objects on to the foreman, and there was an interval of silence while the jury examined them with breathless interest and much facial contortion.

"The next question," resumed Thorndyke, "was, Whence did the murderer obtain these hairs? I assumed that they had been taken from Miriam Goldstein's hair-brush; but the sergeant's evidence makes it pretty clear that they were obtained from the very bag of combings from which he took a sample for comparison."

"I think, Doctor," remarked the coroner, "you have disposed of the hair clue pretty completely. May I ask if you found anything that might throw any light on the identity of the murderer?"

"Yes," replied Thorndyke, "I observed certain things which determine the identity of the murderer quite conclusively." He turned a significant glance on Superintendent Miller, who immediately rose, stepped quietly to the door, and then returned, putting something into his pocket. "When I entered the hall," Thorndyke continued, "I noted the following facts: Behind the door was a shelf on which were two china candlesticks. Each was fitted with a candle, and in one was a short candle-end, about an inch long, lying in the tray. On the floor, close to the mat, was a spot of candle-wax and some faint marks of muddy feet. The oil-cloth on the stairs also bore faint footmarks, made by wet goloshes. They were ascending the stairs, and grew fainter towards the top. There were two more spots of candle-wax on the stairs, and one on the handrail; a burnt end of a wax match halfway up the stairs, and another on the landing. There were no descending footmarks, but one of the spots of wax close to the balusters had been trodden on while warm and soft, and bore the mark of the front of the heel of a golosh descending the stairs. The lock of the street door had been recently oiled, as had also that of the bedroom door, and the latter had been unlocked from outside with a bent wire, which had made a mark on the key. Inside the room I made two further observations. One was that the dead woman's pillow was lightly sprinkled with sand, somewhat like silver sand, but greyer and less gritty. I shall return to this presently.

"The other was that the candlestick on the bedside table was empty. It was a peculiar candlestick, having a skeleton socket formed of eight flat strips of metal. The charred wick of a burnt-out candle was at the bottom of the socket, but a little fragment of wax on the top edge showed that another candle had been stuck in it and had been taken out, for otherwise that fragment would have been melted. I at once thought of the candle-end in the hall, and when I went down again I took that end from the tray and examined it. On it I found eight distinct marks corresponding to the eight bars of the candlestick in the bedroom. It had been carried in the right hand of some person, for the warm, soft wax had taken beautifully clear impressions of a right thumb and forefinger. I took three moulds of the candle-end in moulding wax, and from these moulds have made this cement cast, which shows both the fingerprints and the marks of the candlestick." He took from his box a small white object, which he handed to the coroner.

"And what do you gather from these facts?" asked the coroner.

"I gather that at about a quarter to two on the morning of the crime, a man (who had, on the previous day visited the house to obtain the tress of hair and oil the locks) entered the house by means of a latchkey. We can fix the time by the fact that it rained on that morning from half-past one to a quarter to two, this being the only rain that has fallen for a fortnight, and the murder was committed at about two o'clock. The man lit a wax match in the hall and another halfway up the stairs. He found the bedroom door locked, and turned the key from outside with a bent wire. He entered, lit the candle, placed the box and hassock, murdered his victim, washed his hands and knife, took the candle-end from the socket and went downstairs, where he blew out the candle and dropped it into the tray.
