It"s an early autumn day like any other as Miles Avery drives his wife, Jacqueline, to the station. There"s a smattering of rain in the air, the traffic is in its usual snarl, and the radio"s churning out the latest news. Nothing remarkable crops up in conversation, nor do either of them appear anything other than their normal selves. At the station, Miles draws up just past the taxi rank. Jacqueline gets out, takes an overnight bag from the back seat, then turns towards the platforms. This is the last anyone sees of her. Three weeks after her disappearance, Miles calls the police. Enquiries are made, but there is no evidence of her boarding a train, or even entering the station. Very soon the finger of suspicion starts to turn towards Miles, and as dark secrets from the past start to merge with those of the present, the great love he has been trying to protect is not only revealed, but also thrown into terrible jeopardy.
