Tangled Trails is a fairly straightforward detective novel with little in the way of subplots, so I don't want to give away too much of the story and spoil it for readers. Suffice it to say, then, that when Kriby Lane discovers that James Cunningham has been brutally murdered, and is seen exiting the deceased's apartment in an unconventional manner, he finds himself at the top of the list of suspects and is determined to clear himself by bringing the real murderer to justice, all while trying to keep Esther McLean's (made pregnant out-of-wedlock by Cunningham) name out of it lest she forever be dishonored.

The author's prose style combines telling with showing; for example, "It was characteristic of him that he did not fly wildly into the night. His brain functioned normally, coolly." Tangled Trails is a book to have fun reading (Barry Ergang).

William MacLeod Raine (June 22, 1871 - July 25, 1954), was a British-born American novelist who wrote fictional adventure stories about the American Old West.

Raine was born in London, the son of William and Jessie Raine. After his mother died, his family migrated from England to Arkansas when Macleod was ten years old, eventually settling on a cattle ranch near the Texas-Arkansas border. In 1894, after graduating from Oberlin College, Macleod left Arkansas and headed for the western U.S. He became the principal of a school in Seattle while contributing columns to a local newspaper. Later he moved to Denver, where he worked as a reporter and editorial writer for local periodicals, including the Republican, the Post, and the Rocky Mountain News. At this time he began to publish short stories, eventually becoming a full time free-lance fiction writer, and finally finding his literary home in the novel. His earliest novels were romantic histories taking place in the English countryside. However, after spending some time with the Arizona Rangers, Macleod shifted his literary focus and began to utilize the American West as a setting. The publication of "Wyoming" in 1908 marks the beginning of his prolific career, during which time he averaged nearly two western novels a year until his death in 1954. In 1920 he was awarded an M.L. degree from the University of Colorado where he had established that school's first journalism course. During the First World War 500,000 copies of one of his books were sent to British soldiers in the trenches. Twenty of his novels have been filmed. Though he was prolific, he was a slow, careful, conscientious worker, intent on accurate detail, and considered himself a craftsman rather than an artist.

In 1905 Mr. Raine married Jennie P. Langley, who died in 1922. In 1924 he married Florence A Hollingsworth: they had a daughter. Though he traveled a good deal, Denver was considered his home. Raine died on July 25, 1954 and is buried at Fairmount Cemetery in Denver, Colorado. He was posthumously inducted into the Hall of Great Westerners of the National Cowboy and Western Heritage Museum in 1959.
