The Gripping Beast — Peter Craigie

Terry Lennox, business consultant and slightly tarnished white knight, finds himself caught up in a bewildering and dangerous world of financial and sexual corruption at the secret heart of Edinburgh's well-bred business community. Wrestling with conflicting loyalties, his attempts to unravel the truth lead him into ever more sinister secrets. International finance, a bizarre piece of Viking jewellery, the dark side of Brussels and a weird mountain fastness in Switzerland are all part of the mystery, which comes to a violent conclusion in the icy waters around Orkney.
