A series of ugly killings has shattered the orderly workings of the
Hampstead police station. And truth be told, they have shattered the
confidence of the lead investigator on the case, who has long taken
pride in his old-school "copper's nose." When yet another body turns up,
he's forced to give way to a new chief with fancy new detecting
techniques. But when those, too, prove unequal to the task, the police
are stymied. So they reach back to the past, invoking the skills of one
of the great Gentleman Sleuths. Is this nutty? No doubt. But Lord Peter
Wimsey always got his man.
