Sgt. Troy (Daniel Casey) sadly leaves the Midsomer team in this episode, though not before having to cope with some dramatic events. Troy wins a promotion to inspector but before he can decide on his future, the Midsomer canal tunnel collapses during a restoration project, revealing ancient human bones with a recent skeleton hidden among them. As Barnaby investigates, Troy is sent to the woods near Midsomer Worthy where Tom (David Bradley - "Argus Filch" in Harry Potter), has been attacked by a group of youths. Then one of the teenagers is caught in a man trap and shot dead. Is Tom responsible? This episode features Henry Cavil (Man of Steel).
