An archaeologist is poisoned during a dig, and with only two suspects and a quick confession, it looks like this is going to be an open-and-shut case.

Meanwhile, Neville and Florence realise they might get along better than they originally thought, although the DI's attempts to embrace island life do not find favour with the Commissioner.
