At the end of the working day, Christopher is looking over the ghosts of his occupancy of some rooms on Harley Street, before moving up the road to different chambers, and pastures new. He's half impelled and half reluctant to revisit a pair of audio cassettes, on which are interviews by him and someone else of a woman called Louise, who was arrested in Italy in the 1980s for the double murder of two close friends, Kate and John. Hardly aware he's being snowed in by a London blizzard and the usual British response to any bad weather, he spontaneously provides shelter to a flame-haired beauty, Kay, who provokes him into playing the tapes. It's an occurrence which changes him much more profoundly than he does others at the therapist's couch. Indeed, the closer he gets to Kay, the closer he gets to the voice of the victim from decades ago. What on earth could be the connection?
