Western author 1956.
Author of the book Claws of the Cougar, published in 1951 by Werner Laurie.
The auction sale of the collection of Reginald Martin's books (Source 4) lists Scott Martin as one of his pen-names.
The publishing firm Werner Laurie were being run by George Greenfield in the early 1950s. They published successful series' of Westerns under another two of Reginald Martin's pen-names, Hank McCoy and Brett Cameron.; the former ran to six books, the latter to four. It's possible that the Claws of the Cougar was intended as the first of another series; but it failed to take hold. The book was published again, later, as a Nelson Western paperback.
