Daisy has a lot to celebrate this summer. She's supervising a special tea event to help commemorate the 100-year-anniversary of her town's historic covered bridge. But the main event is her upcoming wedding to her beloved fiancé Jonas. Somehow Willow Creek's busiest brewer of specialty teas and amateur sleuth still finds time to be a guest on local journalist Trevor Lundquist's crime podcast to discuss the last murder she solved.

After the podcast, Trevor receives an anonymous tip from a caller who claims a travel chest that's about to be auctioned holds a clue to a twenty-year-old unsolved murder. Is it a hoax or a genuine lead? When a body turns up in Willow Creek, Trevor suspects a connection between this current homicide and the cold case. Has the murderer killed again to cover their tracks? Now Daisy has another mystery steeping and Trevor may just have his next podcast . . .
