It's like finding the tomb of Tutankhamun! And it's a particularly good one. Hilda persuades Rumpole to come on a "second honeymoon" on a cruise to the Greek islands. (They'd had to come home early from their first honeymoon as they ran out of money.) Rumpole just wants a holiday from judge Graves. Whaddaya know? Judge Graves is on board, taking a holiday from Rumpole.
Rumpole lurks out of site, while Hilda dresses in her best and mingles at the cocktail parties. She quickly chums up with a mystery writer and his irritating personal assistant, and an insurance man turned vicar who has just got married.
They are all serenaded by a (surprisingly good) singer who belts out the golden oldies. Rumpole's cover is blown, and he comes out of hiding, but the newly wed Mrs Britwell develops a mysterious sickness and disappears from view. The mystery writer suspects the Rev of making away with her. He, Rumpole and Graves form an unlikely investigation committee.
Eventually Rumpole solves the mystery in an effective and somewhat surreal denouement, and the Rumpoles set off to shop in Mykonos.
PS Hilda looks stunning in fancy dress as Britannia, while Rumpole wears an eyepatch as a pirate.
