Painted Lies — Gillian Larkin

A short mystery with ghosts.

Grace Abrahams helps ghosts who can't move on until their problems have been solved. The ghosts she meets are attached to items found at storage locker auctions.

Grace is faced with a difficult case this time as she can't see the ghost who now needs her help. The ghost communicates by causing figures in paintings to move. Grace studies the paintings, and the pieces of the puzzle slowly come together.

When Grace works out why the ghost needs help, she's furious and has to take drastic action.
