Another successful work is the eighth Basil Willing novel, "Through a Glass, Darkly" (1950), a supernatural puzzle in the tradition of John Dickson Carr. "If you want to scare yourself still in bed, it's just the thing for you," the English writer Pamela Hansford Johnson said of the book. Boucher and McComas praised the novel as "an eerie study of the phenomenon of the Doppelganger, . . . handled with such disquieting ambivalence that the 'rational' solution seems only an instance of man's folly in the face of the unknowable.".
