The Girl in the Wall — Alison Preston

After leaving the Winnipeg Police force, former Inspector Frank Foote has gone into home renovations. Tearing down a wall on a Norwood Flats job one day, he and his partner come across the skeleton of a small female who has been imprisoned there. They alert the police, who confiscate their tools and remove them from the crime scene. Frank doesn't tell them about the photograph he's found tucked in the wall space with the young woman.
