Evelyn Dunmore returns to her bombed family estate in 1946, determined to lay her past to rest. When half-burned letters signed only "M" surface in the hearth, she assumes the worst—that her late husband, Captain Arthur Dunmore, harbored a hidden betrayal. Haunted by guilt and driven by fear, she destroys every scrap of paper, then sets out across village and countryside in search of answers she hopes will clear her name.

As Evelyn follows cryptic clues through rain-soaked platforms, abandoned cottages, and whispered village testimonies, she discovers more than lost correspondence. Each fragment deepens her dread, suggesting an unthinkable connection between the woman she thought she was and the shadow she fought to escape. With every burning ember and every recovered confession, the line between victim and perpetrator blurs, and Evelyn must confront a secret more dangerous than infidelity: the hidden fractures in her own memory.

Suspense builds as Evelyn races to piece together a shattered identity before the final spark of truth is silenced forever. With a mounting sense of dread and a storm gathering on the horizon, she grapples with the price of redemption—and wonders if some flames can never be doused.

Who is that other woman in the ashes, and how far will Evelyn go to reclaim the truth she once tried to destroy?
