After a year — a year, people — of mind-numbing repetition and drudgery against a background of tragedy, Below Suspicion (1949), John Dickson Carr’s forty-sixth book in twenty years and the 18th to feature Dr. Gideon Fell, was exactly what I needed…for the simple reason that it is so very, very different. Ten years from now I could reread this and be appalled that I ever thought it so great, but right now it is manna from heaven: eerie, baffling, infuriating in many ways, and fascinating given the direction we know Carr’s career took from this point in how it blends the classic detection he had excelled in with the historical mysteries he was about to launch himself into.
