The boy, a thin white-faced, sharp-eyed London street urchin, seemed curiously out of place in the handsomely furnished office, with his legs tucked up under the carved rail of a fine old oak chair, and his big dark eyes fixed intently on Crewe's face. The tie between him and the detective was an unusual one. It dated back some twelve months, when Crewe, in the investigation of a peculiarly baffling crime, found it advisable to disguise himself and live temporarily in a crowded criminal quarter of Islington. The rooms he took were above a secondhand clothing shop kept by a drunken female named Leaver; a supposed widow who lived at the back of the shop with her two children, Lizzie, a bold-eyed girl of 17, who worked at a Clerkenwell clothing factory, and Joe, a typical Cockney boy of fourteen, who sold papers in the streets during the day and was fast qualifying for a thief at night when Crewe went to the place to live.
Crewe soon discovered, through overhearing a loud quarrel between his landlady and her daughter, that Mrs. Leaver's husband was alive, though dead to his wife for all practical purposes, inasmuch as he was serving a life's imprisonment for manslaughter. A fortnight after he had taken up his temporary quarters above the shop the woman was removed to the hospital suffering from the effects of a hard drinking bout, and died there. The girl disappeared, and the boy would have been turned out on the streets but for Crewe, who had taken a liking to him. Joe was self-reliant, alert, and precocious, like most London street boys, but in addition to these qualities he had a vein of imagination unusual in a lad of his upbringing and environment. He devoured the exciting feuilleton stories in the evening papers he vended, and spent his spare pennies at the cinema theatres in the vicinity of his poor home. His appreciation of the crude mysteries of the filmed detective drama amused the famous expert in the finer art of actual crime detection, until he discovered that the boy possessed natural gifts of intuition and observation, combined with penetration. Crewe grew interested in developing the boy's talent for detective work. When the lad's mother died Crewe decided to take him into his Holborn offices as messenger-boy. Crewe soon discovered that Joe had a useful gift for "shadowing" work, and his street training as a newspaper runner enabled him not only to follow a person through the thickest of London traffic, but to escape observation where a man might have been noticed and suspected.
"Well, Joe," said Crewe, as the boy entered on the heels of Stork, "I have a job for you this morning. I want you to find the glove corresponding to this one."
Crewe, having finished his examination of the glove, handed it to the boy, whose first act was to slip it on his left hand and move his fingers about to assure himself that they were in good working order in spite of being hidden. It was the first occasion on which Joe had worn a glove.
"It was found in the room in which Sir Horace Fewbanks was murdered," continued Crewe. "The other one was not there. The question I want to solve is, did it belong to Sir Horace, or to some one who visited him on the night he was murdered? The police think it belonged to Sir Horace because it is the same size as the gloves he wore, and because Sir Horace's hosier stocks the same kind—as does nearly every fashionable hosier in London. They think he lost the right-hand glove on his way up from Scotland. It will occur to you, Joe, though you don't wear gloves, that it is more common for men to lose the right-hand glove than the left-hand, because the right hand is used a great deal more than the left, and even men who would not be seen in the street without gloves find there are many things they cannot do with a gloved hand. For instance, to dive one's hand into one's trouser pocket where most men keep their loose change the glove has to be removed."
"Then the gentleman would take off his right glove when he paid for his taxi-cab from St. Pancras," said Joe, who was familiar through the accounts in the newspapers with the main details of the Fewbanks mystery.
"Right, Joe," said his master approvingly. "And in that case he dropped the glove between the taxi-cab outside his front gates and his room, and it would have been found. I have made inquiries and I am satisfied it was not found."
"He might have lost it when he was getting into the train at Scotland," suggested the lad. "He had to change trains at Glasgow—he might have lost it there."
"That is a rule-of-thumb deduction," said Crewe, with a kindly smile. "It is good enough for the police, for they have apparently adopted it, but it is not good enough for me. What you don't understand, Joe, is that an odd glove is of no value in the eyes of a man who wears gloves. He doesn't take it home as a memento of his carelessness in losing the other. He throws it away. Therefore if this is Sir Horace's glove he took it home because he was unaware that he had lost the other. He would put on his gloves before leaving the train at St. Pancras. And he would pull off the right-hand one—he was not left-handed—when the taxi-cab was nearing his home so as to be able to pay the fare. Therefore, if it is Sir Horace's glove the fellow to it was dropped in the taxi-cab, or dropped between the taxi-cab and the house. If the glove had been lost at the other end of the journey in Scotland Sir Horace would have flung this one out of the carriage window when he became aware of the loss. As I have told you no glove was found between the gate at Riversbrook and the room in which Sir Horace was murdered. I got from the police the number of the taxi-cab in which Sir Horace was driven from St. Pancras, and the driver tells me that no glove was left in his cab. So what have we to do next, Joe?"
"To find the missing glove? It's a tough job, ain't it, sir?"
