Sir Lawrence Linwood is dead. More accurately, he was murdered—savagely beaten to death in his own study with a mediaeval mace. The murder calls home his three adopted children: Alan, an archeologist; Roger, an engineer; and Caroline, a journalist. But his heirs soon find that his last testament contains a strange proviso—that his estate shall go to the heir who solves his murder.

To secure their future, each Linwood heir must now dig into the past. As their suspicion mounts—of each other and of peculiar strangers in the churchless town of Linwood Hollow—they come to suspect that the perpetrator lurks in the mysterious origins of their own birth.
