The past can be a killer.

When the dismembered body of a notorious banker washes up on the beach at Luss, DCI John Lomond finds a sinister message carved into the dead man's forehead.

And the same message has just been found on a tortured lawyer in Gullane on the east coast.

With a twisted vigilante on the loose, and a brewing scandal threatening to pull his Major Investigations Team apart, they and Lomond must join forces with a team from Edinburgh - led by Lomond's ex.

But like the killer they're hunting, she's not ready to leave the past behind.

Now, as the body count rises, Lomond's past hasn't just come back to haunt him. It could be the death of him.

Shot through with dark Glaswegian humour and thrilling twists, Andrew Raymond captures the voices of his beloved home city, taking you into its hidden depths, and the iconic hills and glens surrounding the nearby bonnie banks of Loch Lomond.

If you like writers like JD Kirk, Ian Rankin, David J. Gatward, Val McDermid, Mark Billingham, and Stuart MacBride, this addictive thriller will have you gripped until its explosive, gut-wrenching climax.
