The peace of a beautiful Scottish island is shattered by a brutal murder among standing stones. For Burke and the team, on a rare investigation away from Glasgow, the slaying has all the hallmarks of a ritual killing.
But the unknown victim's corpse has another secret to reveal – a poisonous bite by a tropical South American spider.
As Reid and Ross struggle to get to grips with staying on the island, they begin to piece together bits of the deadly puzzle with the help of the local clergyman Rev Campbell and pub landlady Shona.
Back in the big city, Burke and Fraser's enquiries into the dead man's murky underworld past look like they're heading nowhere fast until drugs squad Detective Sergeant Duggan comes up with some shocking new information.
But the stakes are getting higher. Another islander knows too much and has gone missing.
Soon, Ross and Reid find themselves on an isolated island miles from home, in a race against time to confront not one, but two, ruthless killers.
