Barnaby and Troy tackle two separate cases as Troy prepares to leave Midsomer after his promotion to DI.

A cave in of a local canal tunnel under restoration reveals the skeletons of eight individuals. While most of the skeletons are from a cave in when the canal was under construction in the 19th century, one is obviously of a more recent vintage. Dental records identify him as Eric Edwards who was reported missing in 1965. DCI Barnaby delves into the history of the canal to see if he can find a connection. DS Troy is over the moon when he learns that he has qualified as a Detective Inspector and that there may be a job for him in another county. In what may be his last case in Midsomer, he follows up on an anonymous tip that teenagers are harassing a local hermit, Tom. When one of those teenagers is shot through the head, Barnaby leaves "Inspector" Troy in charge of the case.—garykmcd

Several skeletons are discovered in a tunnel during a canal restoration project near Midsomer Worthy. DCI Barnaby begins his investigations and discovers that one skeleton has modern dental work. Meanwhile, DS Troy has been promoted to Inspector. He begins his last case in Midsomer, investigating the murder of a teenager, Simon Mayfield (played by Henry Cavill), who had been shot with a gun that he and his friends had been using the previous night. The two detectives discover their cases are linked, and uncover a web of lies, affairs, and domestic arguments alongside a mysterious recluse with a hidden past.

When some skeletal remains are found inside a bricked up wall of a canal tunnel, Barnaby takes on the challenge of finding the cause of death for one of them who was killed decades after the others (who presumably died in a cave-in.) Meanwhile Troy investigates his last case in the area -- the killings of young men who were known to be harassing a local homeless man -- and dealing with the resentment of his former co-workers now that he has been promoted to Inspector.—Ron Kerrigan <mvg@whidbey.com>

The Barnaby-Troy partnership is about to come to an end, as Troy has passed his inspector's exam and is moving on. However, the murderers of Midsomer go on piling up the bodies. Joyce Barnaby gets trapped in a fallen canal tunnel, and in getting her out seven skeletons come to light in a hidden chamber. Meanwhile, two local tear-aways are shot dead in the woods at Midsomer Worthy, and a tramp called Tom is accused of the killings. While Troy looks into the shootings, Barnaby wrestles with an old mystery. And although six of the skeletons found in the tunnel date from the 18th century, one is much more recent.—Anonymous
