When the war breaks out, Rose, a well-to-do widower with a young son, Christopher, volunteers for the Auxiliary Fire Service in London, and is trained under a professional fire officer, Pye. The two men discover that a quite different link already exists between them: it was Pye's strange, disturbed sister who once upon a time abducted Christopher and kept him in her room until Pye rescued the terrified child. In the apocalyptic atmosphere of the Blitz the relationship between the two men develops as each of them grapples with his own troubled emotional attachments, the one to his dead wife, the other to his unhappy sister. Inevitably matters come to a head when history shows signs of repeating itself. The subtle handling of relationships, the brilliance of the dialogue and description - including one of the best accounts ever written of London under the Blitz - established Caught as one of Henry Green's most powerful novels.
