But weeks before the grand opening, her shop is broken into and torn apart. Mary is shocked, but she's even more stunned to discover that the only thing the intruder stole was an old, dusty photograph of the storefront. Who would have taken it, and why? With the help of her sister, a childhood friend, and decades of reading mystery novels, Mary searches for answers.
