When Max Easterbrook arrived in London on a month's leave, he was astounded to find George Lambert, his best friend, in prison on a charge of wife-murder. The police were satisfied that here was a clear case of the eternal triangle; no need to look far for the murderer, for George was not exactly weeping tears at his wife's sad demise. But Max was sure George was not the man to murder one woman in order to marry another. He was not nearly so sure that the large and lazy Hilda was not a natural murderee.
