Wycliffe tackles a case which reaches back down the generations ... When Cedric Tremain is charged with murdering his father by booby-trapping his fishing boat, all the locals are agreed that he is an unlikely murderer.
But the case against him is strong: he has the motive, the opportunity and the know-how; not to mention the fact that there is some hard circumstantial evidence against him.
So Cedric is arrested. But Chief Superintendent Wycliffe has a strong sense that something about the case just doesn't fit.
As he quietly continues his investigations a confusing picture emerges.
Twenty years ago Cedric's cousin was convicted of strangling his girlfriend and served fourteen years of a commuted death sentence.
While the wheels of justice begin to grind Wycliffe searches for a link between past and present ?
