In Gallows Hill, Dr Clare Hart investigates a cold case – the skeleton of a young woman murdered twenty years earlier – with Riedwaan Faizal. At the same time, she is helping a troubled young artist, Sophie Brown, identify a malignant stalker. The two are linked, and both Clare and Sophie are in grave danger. Clare discovers that the young woman whose remains are uncovered in the burial grounds near Gallows Hill is Astrid Brown, Sophie’s mother, who has been missing for two decades. Her murderer is now stalking Sophie, and if needs be he will kill again. And again. In fact, he will kill as often as it takes to hide the secret he so neatly buried with Sophie’s mother these last twenty years.
