After a year of marriage - and numerous adventures - Lady Julia and Brisbane hope for a quiet, intimate Christmas together - until they find themselves at her father's ancestral estate, Bellmont Abbey, with her eccentric family and a menagerie of animals. Nevertheless, Julia looks forward to a lively family gathering - but amongst the celebrations, a mystery stirs. There are missing jewels, new faces at the Abbey, and a prowling ghost that brings back unwelcome memories from a previous holiday - one that turned deadly. Is a new culprit recreating crimes of the past? And will Brisbane let Julia investigate?

It's the autumn of 1890, and almost a year has passed since - much to their surprise - Lady Julia and Nicholas became parents.

What could go wrong? Combine the close-knit chaos of village life, pagan traditions bursting through staid Victorian conventions, and the congenial madness that tends to swirl around Lady Julia's family and you get an unforgettable wedding.
