Several businessmen have been killed, the murderer having apparently clawed them to death so that the initial suspect is an author who owns a bird of prey and had a grudge against a victim who ran a publishing house. However, the discovery of a comic called 'The Winged Avenger' featuring a super-hero is found by the latest victim. And could the invention of Professor Poole, boots that allow the wearer to climb walls and scale ceilings, be involved?
