Repairs are under way at Rebecca Anderson's gourmet popcorn shop. With production of her tasty treats on hold, Rebecca has plenty of time to read the old diary she discovered hidden in the shop's walls. It's a fun peek into her town's history... until the diary's abrupt ending leaves Rebecca wondering whether she's actually stumbled upon a cold case. Unfortunately for Rebecca, mysteries are popping up right and left. When local busybody Lloyd McLaughlin is found dead, the police suspect he was poisoned by Rebecca's popcorn. But Rebecca has only made one batch of popcorn recently, and it wasn't intended for Lloyd. Nothing about Lloyd's death makes sense - until Rebecca discovers a startling connection between the missing diary-writer and the murdered man. Now, with her reputation on the line, Rebecca must discover who's been cooking up murder - both in the past and in the present.
