The dog days of summer are back, and Darwin Winters, pet psychic, is excited to attend the St. Pete Seafood Festival with her sister. Unfortunately, the festival gets shut down early when a despised, local food critic dies from ingesting pufferfish toxin while judging the Chef’s Golden Lobster Contest.

When Hana Ishida, the chef who served pufferfish to the victim, is taken in for questioning, Darwin agrees to dog-sit the woman’s dachshund, Daisy. Darwin receives a vision from Daisy showing Hana in a heated argument, but for Daisy’s sake, Darwin desperately wants to dig up the truth and help her boyfriend, Detective Will Blake, prove Hana’s innocence.

Though Will does have a few fishy restaurant owners on his suspect list, none of the clues are pointing to anyone but Hana. Can Darwin help him reel in the right suspect? Or will this killer be the one that got away?
