Clyde Allison was a pseudonym for William Knoles. Most famous for the 0008 series, Knoles has often been regarded as one of the few great sleaze writers. He mostly published with William Hamling's various houses, writing a book almost every month between 1960 and 1968. Knoles was a reader for Scott Meredith Literary Agency when Meredith began supplying Hamling with manuscripts. Beginning with The Lustful Ones (NB1525) in 1960, Knoles became one of Hamling's most prolific and creative authors. He felt hemmed in by the sleaze genre, but his hopes of writing more literary fiction were consistently quashed by the need for a quick paycheck. As far as hack writing goes, in the early days of sleaze writers were paid extremely well, but Knoles still spent it faster than he could bring it in. Bipolar and by some accounts an alcoholic, Knoles committed suicide in 1970.
