Unhallowed Ground

Description for UNHALLOWED GROUND by Heather Graham:

A House Can Be Only As Evil As the People Who Lived There

When Sarah McKinley is finally able to buy and restore the historic Florida mansion that she has always loved, she dismisses the horror stories of past residents vanishing and a long-dead housekeeper who practiced black magic. Then, in the midst of renovations, she makes a grim discovery. Hidden within the walls of Sarah's dream house are the remains of dozens of bodies -- some dating back over a century.

The door to the past is blown wide open when Caleb Anderson, a private investigator, shows up at the mansion. He believes several current missing-persons cases are linked to the house and its dark past. Working together to find the connection and stop a contemporary killer, Sarah and Caleb are compelled to research the history of the haunted house, growing closer to each other even as the solution to the murders eludes them.

But there is one who knows the truth...a spirit who follows every move they make. Soon Caleb begins to fear that if he can't stay a step ahead, he could lose Sarah to a killer with an ability to transcend time in a quest for blood and sacrifice.

This is #3 in Harrison Investigations.
