Seven Bengal tigers are the star attraction of Carey's Circus. Their trainer is the fearless Anton, whose work demands absolute fitness and the steadiest of nerves. When Anton is found lying dead in the tigers' cage, it seems that he has lost control and been mauled by the tigers – but Detective Inspector Minto of Scotland Yard is not convinced. Minto's investigations lead him deep into the circus world of tents and caravans, clowns and acrobats, human and animal performers. No one is above suspicion. Carey, the circus-owner with a secret to hide; Dodo, the clown whose costume is scratched as if by a claw; and Lorimer, the trapeze artist jealous of his flirtatious wife – all come under Minto's scrutiny as the mystery deepens.
