Jac Thompson thinks she's escaped her neglected childhood in Glasgow. Now she's the perfect employee, waging a one-woman war against untidy desks, long lunch hours and post-its with puppies on them.
When Jac loses her job, her estranged father reappears, claiming to be sober, repentant and ready to help her pick up the pieces. Within days he's betrayed her trust, discovered a skeleton in the walls of her isolated cottage and walled it back up again. When a baby's body is discovered near her childhood home, Jac's father builds a priest's hole in the wall and hides alongside the skeleton.
Who is the baby? Who is the woman in the wall? Jac sets out to discover the identity of both.
Neglect is only the start of it. Like her cottage, Jac's life is built on bones.
The only thing that bothers me is that I don't mention the disembodied voice. But maybe I don't have to. It's not as central to this as it was to the original short story, although it does still feature in the early pages.
