It Was Not So Much a question of "who-done-it" as of "who-done-what." Respectable solicitors do not disappear every day, but Duncan Humby had vanished into thin air while on his way to prepare a new will for James Grossiter--a will in which the crotchety millionaire intended to dispossess all his relations and his manservant in favor of numerous charities. The death from a heart attack of Old Grossiter himself was too much of a coincidence for Carolus Deene, who was called upon to find the missing solicitor, and as he made his way to the remote village of Hallows End, where Humby's car has been seen and where Grossiter was staying, he had a strong feeling of sinister evil and danger . . . a feeling that was soon to be translated into horrible fact.
