Scotland Yard detective Ian Rutledge is assigned one of the most baffling investigations of his careera cold murder case with an unidentified victim and a cold trail with few clues to follow. Chief Inspector Brian Leslie, a respected colleague of Ian Rutledges, is sent to Avebury, a village set inside a great prehistoric stone circle not far from Stonehenge. A young woman has been murdered next to a mysterious, hooded, figure-like stone, but no one recognizes heror admits to it. And how did she get there? Despite a thorough investigation, it appears that her killer has simply vanished. Rutledge, returning from the conclusion of a case involving another apparently unknown woman, is asked to take a second look at Leslies inquiry, to see if he can identify this victim. But Rutledge is convinced Chief Superintendent Jameson only hopes to tarnish his earlier success once he also fails. Where to begin? He too finds very little to go on in Avebury, slowly widening his search beyond the villageonly to discover that unlikelypossibly even unreliableclues are pointing him toward an impossible solution, one that will draw the wrath of the Yard down on him, and very likely see him dismissed if he pursues it. But what about the victimwhat does he owe this tragic woman? Where must his loyalty lie?
