Called in to examine what is left of a body struck by lightning, Tempe traces an unusual tattoo to its source and is soon embroiled in a much larger case. Young men – tourists – have been disappearing on the islands of Turks and Caicos for years. Seven years ago, the first victim was found in a strange location with both hands cut off; the other visitors vanished without a trace. But, recently, tantalising leads have emerged and only Tempe can unravel them.
