It is moderately funny to me that I searched for years for Whistle Up the Devil (1953) by Derek Smith, only to finally run a copy to earth for sensible money — with a dustjacket and everything — in 2014. Then, about two months later, Locked Room International republished it along with all Smith’s crime and detective fiction, and I went from zero copies to two in no time at all. In 2018 I called it one of my fifteen favourite impossible crime novels, and one of those has already dropped off the perch, so revisiting this in January 2026 was fraught with peril. But, well, if anything, a second read has given me even more to enjoy about it, and it thankfully remains available now for you to get it for sensible money…so go, quickly!
