Knightley, H: Groundskeeper's Daughter

The dead can't hurt the living, or can they? Molly Delray's father is the groundskeeper of Smith and Stone Cemetery. When she returns home for Christmas after being away for over a decade, she forgets the rules and disturbs the ghost of Old James. When the ghost's living relative shows up at Molly's doorstep, it's up to her to solve a centuries old murder before the ghost kills again.
