Hot on the heels of an art forger, a member of the Lockwood Antique Hunter’s Agency disappears while investigating an isolated castle deep in Scottish countryside. Freya and Aunt Carole race to her last known location and arrive in the wintry, snow-covered Scottish Borders.

At the castle, they discover that a murdered laird in the vegetable garden and his priceless collection of silverware has been stolen. Local police believe Freya’s missing team member was involved with the robbery and murder...but where is she now?

As a snowstorm descends on the castle, Freya and Carole call in back-up to help uncover what happened that fateful night. As each question is met with more mystery, the clock is ticking to find their friend and the murderer before they are cut off from the outside world.
