Flowers on her grave

"Detective Katie Scott has never seen two people more in love than her aunt and uncle as they danced on the decking the night of their wedding anniversary party. But the next morning, when Katie finds her aunt's body sprawled across the floor, that perfect image is shattered forever. All fingers point to Katie's uncle, Pine Valley's beloved sheriff and protector-after all, his prints are all over the antique knife found at the scene. Grieving, but certain of her uncle's innocence, Katie is consigned to the cold case division after she's discovered searching the house for clues. Does someone want to keep her as far away from this investigation as possible? Ignoring warnings from her team, Katie digs into her uncle's old case files and discovers photographs of the body of a young girl found tied to a tree after a hike in search of a rare flower. Her body is covered with the same unusual lacerations her aunt suffered. Katie knows it can't be a coincidence, but every lead she follows takes her to a dead end. Moments before the sheriff is arrested, Katie realises that a single piece of thread she found at the crime scene could be the missing link that will stitch old crimes to new. But how can she prove her uncle's innocence without throwing herself directly into the line of fire? She doesn't have a choice, he's the only family she has left...." -- Provided by publisher.Some violence and some strong language.
