*Crime, Spies & Sleaze: Five highly collectable 1950s Pan crime/spy books for your consideration in this update: four by Peter Cheyney and one by Arthur Upfield. We’re very pleased to be listing an Upfield title for the first time -The Mountains Have a Secret featuring Inspector Napoleon Bonaparte (Bony). Three of the Cheyneys are in his ‘Dark’ sequence of tough Secret Service Adventures (Dark Wanton and two different editions of Dark Bahama, one with cover art by John Pollack) and the fourth is You’d Be Surprised, featuring inimitable FBI agent Lemmy Caution.
