Here's an example: W. L. Martin was the author of The Shooting of Wild Bill Hickok, a paperback original published by Digit Books in 1960. Here's the blurb:
Many books, both fact and fiction, have been written about the hectic life of the famous Western lawman and gunfighter, Wild Bill Hickok. Little, however, has ever been written about the infamous murder of this bizarre figure of the West by a drifter and penny-ante gun rannie by the name of Jack McCall.Most Western originals published by Digit were published in their Longloop Westerns or Wagon Wheel Westerns series. The Shooting of Wild Bill Hickok just happened to be published after the former folded and before the latter was launched; a handful of Westerns appeared under the Digit imprint in 1960 but only one or two were originals.
__That killing, like the cowardly murder of Jesse James, touched off a series of startling and historical events.
__This Digit Original factual Western presents for the first time the true story behind the murder, and the consequences. As may be expected, murder abduction, rape, love and hate resulted.
The oddity here is that the book lists a number of other titles "by the same author"...
- Night Riders of Tonopah.
- Guns Along the Columbia.
- Indian Agent.
- Arrowhead Justice.
- Johnny Lasher—Gunman.
- Red-River Riders.
What of William L. Martin? Apart from the fact that he was born in 1919, nothing else is known. The Shooting of Wild Bill Hickok contains a brief dedication "to Jane and Vic Rose" but no other clues.
One final mystery. The cover is by American artist Harry J. Schaare and, presumably, originally appeared on an American paperback. Can anyone identify the original book?
More "mysteries that continue to mystify" soon...
