This book was published in 1959. Don Holliday was a name that was used by several writers who were represented by literary agent Scott Meredith. Pseudonyms like Don Holliday were used to protect both the reputations of Meredith and the writers who churned out a book-a-month for publishers like Midwood. Among the writers who were wrote under the name Don Holliday: Hal Dresner, Robert Silverberg, Donald Westlake, and Lawrence Block. While I was doing some research on Midwood and Don Holliday, I came across a post at Vintage Sleaze Paperbacks that attempted to determine which of the Don Hollidays actually wrote Only The Bed.
The cover artist is unknown. I like the way that the bars of the resemble the beds of the prison, suggesting that the couple on the cover as prisoners of their own lust.
