Time is running out for Philip Dryden . . . In the snowbound landscape of the Cambridgeshire fens, a body is discovered, locked in a block of ice. High on Ely Cathedral a second corpse is found, grotesquely 'riding' a stone gargoyle. Journalist Philip Dryden knows he's onto a great story when forensic evidence links both victims to one terrifying event in 1966. But the murders also offer Dryden the key to a very personal mystery. Who saved his life two years ago? And, more importantly, who left his wife to die? The answer will bring Dryden face to face with his own guilt, his own fears - and a cold and ruthless killer . . .
