Our coroner Natasha is at the heart of the inquiry into her brother's recent murder. Arch and Fitz question how the man, who was reported dead over a year ago, re-appeared and who is his killer?

A world-famous violinist and convicted predator dies while performing at his father's funeral, propelling Fitz and Arch into a search for his killer among mourners and those protesting his presence.

When a diver mysteriously drowns, Arch and Fitz are drawn into a world of shipwrecks and plundering, leading them to wonder if the infamous waterway Mouth of Hell has claimed yet another victim.

A hit and run victim causes Fitz to confront his undercover past, and when his ex-partner unexpectedly appears, she joins him and Arch in a race against time to stop a money heist.

When a man is found brutally murdered, Arch and Fitz suspect it is the work of "The Abstract Killer", a serial killer who plagued Saint-Pierre long ago and was believed to be dead.
