2nd in the Lewis Trilogy, I've pretty much started this one straight after the first, The Blackhouse.
From the Blurb:
A body is recovered from a peat bog on the Isle of Lewis. The male Caucasian corpse is initially believed by its finders to be over 2000 years old, until they spot the Elvis tattoo on his right arm. The body, it transpires, is not evidence of an ancient ritual killing, but of a murder committed during the latter half of the 20th century.
