Forensic historian Simon Shaw likes his murders old and cold, and his first case fits the bill. An archeologist friend has found a skeleton with a bullet hole in its skull under historic Bloodworth House, and Simon investigates with his usual doggedness until he discovers that the corpse is Anne Bloodworth, an heiress who disappeared in 1926. Shaw feels compelled to find out who killed her. But this turns out to be more than an academic exercise when someone who wants to hide past secrets tries to murder him!
