When Ellen Peters purchases a box of vintage papers from a local antique shop, she expects to find little more than old photographs, postcards, and forgotten keepsakes.

Instead, she uncovers a collection of letters and diary pages connected to a tragedy that has haunted Driftwood Bay for more than fifty years.

In 1975, seventeen-year-old Rose Whitaker died under mysterious circumstances. Although the case was investigated, questions remained unanswered and rumors lingered long after the town had moved on. Now, hidden among the letters and diary entries, Maggie Allan discovers clues that suggest the truth may have been buried for decades.

As Maggie and her friends piece together the fragments of Rose’s story, long-forgotten secrets begin to surface. Old wounds are reopened, respected members of the community find themselves under suspicion, and memories once thought lost reveal a very different version of the past.

With every letter she reads, Maggie moves one step closer to uncovering what really happened on that summer evening so many years ago. But some secrets have been hidden for a reason, and someone may still be determined to keep the truth from coming to light.

Set against the familiar backdrop of Driftwood Bay, The Mystery of the Unseen Letters is a heartwarming cozy mystery filled with friendship, family secrets, small-town charm, and the enduring power of the past.
