A locked door. A dead man. A bookshelf that isn't what it seems.
When Lady Cecelia Pembroke - amateur sleuth, book restorer, and reluctant magnet for other people's worst-kept secrets - arrives at Thornfield Manor to catalogue a rare manuscript collection, she expects dusty folios, a birthday dinner, and an early night. What she doesn't expect is to find her host dead inside a hidden room sealed from the inside, with no apparent means of escape and no explanation for how anyone could possibly have left.
The local constable calls it a coincidence.
Cecelia calls it nonsense.
Set in the 1920s cozy mystery tradition of the English country house - fires burning in the grates, shortbread on every surface, and a household full of people hiding something - Murder in the Secret Room is a historical cozy mystery where every clue is waiting to be discovered, and readers are invited to solve the puzzle alongside Cecelia.
With a Scotland Yard detective who finds her both frustrating and invaluable, a cat sidekick with an uncanny eye for detail, and a three-hundred-year-old secret hidden beneath the hearthstone of a sealed room, Cecelia must untangle buried loyalties, a trail of forged evidence, and a locked-room puzzle in Wiltshire - before the killer decides she has discovered one secret too many.
Because the hidden room gave up its first secret the morning the body was found. Its deepest secret is still waiting. And someone in this house will do anything to keep it there.
If you love the Golden Age cozy mystery tradition - clever puzzles, atmospheric English settings, and a heroine who solves mysteries through sharp observation rather than luck - you will feel at home here.
This British cozy mystery follows an amateur sleuth with a warm, wry voice who notices the details that others would very much prefer she didn't.
With every clue waiting to be uncovered from the first page, the mystery invites readers to follow the trail of secrets, suspects, and hidden truths until the final reveal.
A slow-burn romance. A clever locked-room puzzle. A community of characters who become familiar faces. And shortbread that is, by every account, exactly right.
Step inside Thornfield Manor. The fire is lit, the mystery is waiting, and the bookshelf in the east library is almost certainly not just a bookshelf.
