The Simney family, of Hazlewood Hall, have a dubious history. Sir George Simney, who was travelling in Australia before the baronetcy fell to him, sleeps with a shotgun by his side. When he is found dead in the library, the Reverend Adrian Deamer will not rest until he has discovered who is responsible. This is an absorbing tale narrated by Simney's widow, Nicolette, and by young Harold, who has just joined the CID.
