Stella Darnell cannot shake her father's legacy. A year after his death, she has discovered what looks like an unsolved case in his darkroom: a folder of unlabelled photographs of deserted streets. But why did her father - a Detective Chief Superintendent - never file them at the station? The oldest photo dates back to 1966, to a day when ten-year-old Mary Thornton was taking her little brother home from school. That afternoon, as the Moors Murderers were sent to prison for life, Mary witnessed something horrible that would haunt her forever. As Stella inches closer to the truth, the events of that day in 1966 will begin to haunt her too. This is the 2nd story in the Detective's Daughter series.
