Clarendon Estate, 1814. A hidden identity. A country house full of suspects. And a killer hiding in plain sight …

For nine months, Juliet Sinclair has lived under an assumed name, searching for the truth behind the murders that shattered her family. Her latest lead brings her to Clarendon Estate, where she serves as lady’s maid to the newly married Lady Leith – and where one cryptic clue suggests that the man responsible may finally be within reach.

At first, Clarendon seems a welcome refuge from the dangers Juliet has faced before. Lady Leith proves an unexpected ally, and life on the estate offers a rare glimpse of peace. But beneath the elegant façade, tensions simmer. A domineering dowager refuses to surrender control of the household, old loyalties run deep, and the arrival of a distinguished house party brings together several men connected to Juliet’s past – each with secrets of his own.

As Juliet’s investigation draws her deeper into a web of hidden messages, blackmail, and betrayal, she discovers that the answers she seeks are far more personal than she ever imagined. Worse still, the trail leads to a man she once trusted – and perhaps even loved.

With danger closing in and a ruthless enemy determined to keep the truth buried, Juliet must risk everything to uncover a conspiracy years in the making. But at Clarendon Estate, every clue comes at a price – and this time, failure could cost her life.

Atmospheric, suspenseful, and rich with Regency intrigue, Clarendon Estate is a compelling installment in the Sinclair Society Mystery series, perfect for readers who enjoy intelligent heroines, country-house mysteries, slow-burn romance, and secrets lurking behind every door.
