There’s nothing so worrisome as a wayward sister. Rona knows that from bitter experience, and many a sleepless night . . .

When she gets a call from the sister of artist Elspeth Wilding — begging her to investigate Elspeth’s sudden disappearance — Rona can’t help but be drawn in.

Headstrong Elspeth’s always been a law unto herself. Now she’s vanished from her remote cottage, leaving her latest masterpiece half-finished on the easel — and her sister desperate for answers.

But not everyone is sorry Elspeth’s gone. Elspeth drove her best — and only — friend to throw herself under a train. No one seems to have a good word to say about the missing woman.

When a dead body is found in Elspeth’s abandoned studio, a disturbing new picture begins to emerge.

Can Rona get to the bottom of it all — before the killer returns to add the final brushstroke?
