Kissing the Gunner's Daughter: Part One - S6.E8

A Kingsmarkham police sergeant dies, carrying a replica gun he had taken from his young son... Then, one year later, Wexford is called to Tancred House, where Davina Flory and her family lie shot dead in a pool of blood. The only survivor is seventeen-year-old Daisy Flory. There are no other witnesses, and the two possible suspects have vanished into thin air. Then a blackmailer is found dangling from a tree... Wexford slowly uncovers a web of motives, greed, illicit sex, and revenge.
