Author Tess Harrow is looking to get back in the town of Winthrop's good graces after she uncovered not one, but two long-forgotten murders. With the perfect plan of combining her new book release with her bookstore's grand opening, she'll have the chance to wine and dine the locals and some big press contacts.

But on the night before the party, Tess is greeted by a surprise: her mother has come for a visit, with her much younger new boyfriend in tow…a boyfriend her daughter Gertrude recognises as the notorious Levi Parker, a man recently connected to the deaths of three elderly widows.

Tess immediately alerts Sheriff Boyd about Levi and his suspicious past, but it's already too late – Levi Parker is found dead, and Tess's mother is starting to look like the prime suspect. Bernadette swears she didn't murder Levi, and Tess is doing her best to maintain her mother's innocence, but too many coincidences keep stacking up. With the whole town seemingly against her family, it's up to Tess to get to the bottom of the story before it's too late.
