A mulberry leaf is a very insignificant thing, but a piece of satin is a highly marketable commodity, with money in it. Henceforth, he regarded himself as a mulberry leaf which his own wit and skill must transform into satin: at the same time he knew that there is another thing, in addition to time and patience, which is valuable to young men of his peculiar qualities, a thing also much beloved by Talleyrand—opportunity. He could find the patience, and he had the time—but it would give him great happiness if opportunity came along to help in the work. In everyday language, Linford Pratt wanted a chance—he waited the arrival of the tide in his affairs which would lead him on to fortune.
Leave him alone—he said to himself—to be sure to take it at the flood. If Pratt had only known it, as he stood in the outer office of Eldrick & Pascoe at the end of a certain winter afternoon, opportunity was slowly climbing the staircase outside—not only opportunity, but temptation, both assisted by the Devil. They came at the right moment, for Pratt was alone; the partners had gone: the other clerks had gone: the office-boy had gone: in another minute Pratt would have gone, too: he was only looking round before locking up for the night. Then these things came—combined in the person of an old man, Antony Bartle, who opened the door, pushed in a queer, wrinkled face, and asked in a quavering voice if anybody was in.
"I'm in, Mr. Bartle," answered Pratt, turning up a gas jet which he had just lowered. "Come in, sir. What can I do for you?"...
At age 20, Fletcher began working in journalism, as a sub-editor in London. He subsequently returned to his native Yorkshire, where he worked first on the Leeds Mercury using the pseudonym A Son of the Soil, and then as a special correspondent for the Yorkshire Post covering Edward VII's coronation in 1902.
Fletcher's first books published were poetry. He then moved on to write numerous works of historical fiction and history, many dealing with Yorkshire, which led to his selection as a fellow of the Royal Historical Society.
Fletcher wrote several novels of rural life in imitation of Richard Jefferies, beginning with The Wonderful Wapentake (1894). Michael Sadleir stated that Fletcher's historical novel, When Charles I Was King (1892), was his best work.
In 1914, Fletcher wrote his first detective novel and went on to write over a hundred more, many featuring the private investigator Ronald Camberwell.
