Bloodlands

When a car belonging to a former IRA man is pulled from the sea in Northern Ireland, Detective Tom Brannick finds an ominous postcard that connects to a shadowy case from the past: an assassin nicknamed Goliath.

Tom reels from the discovery of three bodies buried 20 years ago-one of which may be his wife. Tom and Niamh interview Pat Keenan, the man who was kidnapped, but he won't say who abducted him. Later, Tom confronts Adam Corry, who was hunting Goliath.

As Tom scrambles to cover up what he's done, Adam Corry is deemed a missing person and his house becomes a crime scene. Tom searches for the woman in Pat's car and is shocked to discover her true identity.

Tom's superior is arrested and interviewed, but Tori worries there's not enough evidence for a conviction. Niamh remains unconvinced that they've finally caught Goliath and starts her own investigation.

The killing of a local accountant leads DCI Tom Brannick and DS Niamh McGovern into a web of intrigue surrounding the accountant’s widow, Olivia Foyle.

A raid on an abandoned house uncovers the hiding place of Robert Dardis. Tom is forced to use drastic measures to find the whereabouts of the gold.
