How far would you go to find your missing sister? When DI Thomasine Albright is informed that the remains of her 15-year-old sister have been found, she has the tragic responsibility of breaking the news to her mother. Thomasine promises her mother that she will be the one to find Karen’s killer. But Karen Albright wasn’t the only girl to go missing during that weekend in 1973 … Veronica Lightfoot disappeared too. They’d lived barely four miles apart, yet apparently never met. Suddenly there is a new question, was Veronica involved in her Karen’s death? Is that why she vanished? DI Mel Philips is handed the original case file and begins a new investigation. Unwilling to be side-lined, Thomasine decides to go it alone. As the case unfolds, Thomasine realises that there may be other victims. Can she find them too?
