Roger Querrin died alone in a locked and guarded room, beyond the reach of human hands. Algy Lawrence could not explain the mystery of this “miracle” murder. And then, faced with a second crime which also could not possibly have been committed, he began to wonder, at last, if somebody had conjured up an invisible demon who could blast out locks and walk through solid walls… One of only two novels written by the very talented Derek Smith, and the only one published in his lifetime, this masterpiece of impossible crime fiction is also available as part of the Derek Smith Omnibus published by LRI, containing all his known writings.
