In London, 1938, young and idealistic lawyer Edmund Ibbs is trying to find any shred of evidence that his client Carla Dean wasn't the one who shot her husband dead at the top of a Ferris Wheel. But the deeper he digs, the more complex the case becomes, and Edmund soon finds himself drawn into a nightmarish web of conspiracy and murder. Before long he himself is implicated in not one but two seemingly impossible crimes.

First, a corpse appears out of thin air during a performance by famed illusionist "Professor Paolini" in front of a packed auditorium at the Pomegranate Theatre. Then a second victim is shot dead in a locked dressing room along one of the theatre's winding backstage corridors. Edmund is in exactly the wrong place at the wrong time, and attracts the suspicion of Scotland Yard inspector George Flint. Luckily, conjuror-turned-detective Joseph Spector is on the scene. Only Spector's uniquely logical perspective can pierce the veil of deceit in a world of illusion and misdirection, where seeing is not always believing.

Tom Mead continues to pay homage to the locked room mysteries of the Golden Age in this second Joseph Spector novel.
