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.
