He needed the money. He needed to kill his siblings.
Ken Bishop's mother had died, leaving an equal share of her estate to each of her surviving children. That meant Ken Bishop would not receive enough to cover his debts. That meant at least some of his siblings needed to die. One of his sisters was in a nursing home, an easy target. She was the first.
BCA Agent Danny Carlisle is given the assignment to look into the death of the woman. A woman with dementia given only days to live. A woman whose family felt relief to see her suffering end. They all assumed she had died of her illness, but Carlisle discovers she was murdered.
Bishop kills a brother next, only to discover someone has killed a sister. And then another. And now Bishop is wondering if he will be next.
