Double Trouble

It was the 1950s in postwar America and paperback books were the hot new product in the publishing industry. Of course to stand out from the crowd and sell one needed a gimmick. Into this newly exuberant market came a publishing house named Ace Books with the seductive promise of two books for the price of one. It also had the eye-catching premise of two separate covers joined at the spine like Siamese twins. Finished with one book? Flip the paperback over and begin again with a new novel complete with its own package. It was something completely different - and it sold! Double Trouble tours the short yet popular era of the Ace Mystery Doubles and includes both author-title and title indexes for easy reference.
