A brand new novel in the “sometimes whimsical, often insightful, always absorbing” (Shelf Awareness) Dove Pond series that follows a gifted historian investigating the mystery of a love story lost to time.

When an antique tin of love letters is found hidden in her family home, noted historian Tay Dove rushes home to Dove Pond to investigate. Tay is still reeling from a romantic betrayal, so she's relieved to refocus her energies on her latest project: a biography of her great-great-grandmother Sarafina, a star reporter who began her career in Dove Pond in the late 19th century before abruptly leaving town.

Tay believes the letters could be the key in solving what happened, but they only add to her questions—especially when they reveal a forbidden love affair with William Day, a wild youth who took part in a notorious train robbery. Some answers might be found in eighty-year-old Rose Day's bookshop, which doubles as a town archive, but Rose is curiously resistant to give Tay access. Just when Tay thinks she's reached a dead end, she finds an unlikely ally in Rose's grandson, Luke, a fellow puzzle lover. Together, they set out to uncover what really happened all those years ago…and find the truth behind a love story that could be more precious than gold.
