The Secret Thread, Hardcover

At a lavish summer party on an English country estate, tensions between social classes lead to deadly consequences that won’t stay buried in this twisty, engrossing suspense novel by the author of The Midnight Hour.

Even the darkest secrets unravel in time...

2024: Jo O’Mara, a young writer, lands a job working for Mimi Mott, a wealthy style icon and legendary founder of a decorating empire. Newly widowed and in her seventies, Mimi is preparing to auction off her possessions, through them finally telling the story of her early life. Famously private, Mimi has kept her past shrouded in mystery. Jo doesn’t dare reveal how closely it touches her own.

Tasked with collecting the untold tales behind each auction lot, Jo peels back the layers of Mimi’s origin story and discovers it’s far darker than anyone ever suspected.

1969: Mimi and her sister, Pamela, live in a cramped, musty staff cottage on the grounds of Rushwood, an idyllic English country estate owned by the Caswell family, their demanding new employer. Working alongside their gardener parents, the girls have been raised with their hands in the soil and know only a traditional, simple life—but spirited Mimi hungers for more.

When the Caswells’ adult children, Nancy and Lawrence, arrive at Rushwood for the summer, the sisters are drawn into a privileged, intoxicating world, unsettling their own, and passions spark under the blazing sun—until a shattering death at Rushwood’s high-society party tears Mimi and Pamela apart.

Now time is running out. Jo discovers both a missing auction piece and a missing sister and vows to find them no matter how dark the secret they expose—or the cost to herself.
