A belated honeymoon turns into a busman’s holiday when gardas Siobhán and Macdara Flannery find themselves investigating a dead body found in a fish and-chips shop …

Siobhán’s brother Eoin’s new family restaurant, The O’Sullivan Six, is so close to opening—but waiting on the necessary permits, plus the heat of July in the village of Kilbane in County Cork, is driving everyone a bit mad. Macdara Flannery comes to the rescue with a plan—take a holiday by the sea and stuff themselves with fish and chips to support the struggling business of the aptly named Mrs. Chipper.

But when they arrive, a crowd is gathered in front of the closed shop: a local fisherman with a fresh cod delivery, a food critic, Mrs. Chipper’s ex-husband who’s opening a competing fish-and-chips shop directly across the street, and a repairman to fix the vent for the deep fryer. With Siobhán and Macdara as witnesses, a local handyman gets the locked door open, only to find the proprietor lying dead and covered in flour at the base of a ladder, its rungs coated in slippery fat. Clearly this was not an accidental tragedy …

Even as the local garda take over the murder investigation, Siobhán and Macdara can’t help themselves from placing their long-delayed honeymoon on hold—at least until they can help apprehend an elusive killer.
