And with that he drew from his pockets a pair of thin surgical rubber gloves, both of which were blood-stained, and hurriedly threw them into the fire. On the following evening about six o'clock I was alone in Rayne's chambers when the evening newspaper was, as usual, pushed through the letter-box. I rose, and taking it up glanced casually at the front page, when I was confronted by a startling report. It appeared that just after midnight on the previous night the watchman on duty at the Chartered Bank of Liberia, in Lombard Street, had been murderously attacked by some unknown person who apparently battered his head with an iron bar, and left him unconscious and so seriously injured that he was now in Guy's Hospital without hope of recovery. The bank robbers had apparently used a most up-to-date oxyacetylene plant for cutting steel, and from the strong-room in the basement--believed to be impregnable and which could only be opened by a time-clock, and, moreover, could be flooded at will--they had cut out the door as butter could be cut with a hot knife. From the safe they had abstracted negotiable bonds with English, French and Italian notes to the value of over eighty thousand pounds, with which the thieves had got clear away. The bank robbery was the greatest sensation of the moment. The thieves had cleverly effected an entrance by one of them having secreted himself in a safe in the bank when it had closed. In the morning at nine o'clock when the first clerk, a lady accountant, had arrived, she could get no entrance, so she waited till one of her male colleagues arrived. Then they called a constable, and after half an hour the sensational fact of the unconscious watchman and the rifled strong-room became revealed. The newspaper report concluded with the following sentences: "It is evident that one of the thieves cut his hand badly, for we understand that the detectives of the City police have found blood-stained finger-prints of four distinct fingers upon the door and in other parts of the strong-room. These, of course, have already been photographed, and in due course will be investigated by that department of Scotland Yard which deals with the finger-prints of known criminals." With the knowledge of the injury to Duperre's hand I felt confident that the great _coup_ was due to him. And I was not mistaken. The bank thieves had got clear away, it was true, but they had left those tell-tale finger-prints behind! As everyone knows, the ridges and whorls upon the hands of no two men are alike, therefore it seemed clear that Scotland Yard, now aroused, would very quickly--owing to its marvelous classification of the finger-prints of every criminal who has passed through the hands of the police during the past quarter of a century--fix upon the person who had laid his hands upon the steel safe door. An hour after I had read the report in the paper, Duperre rang me up.
