Lucky Miss Seeton is thrilled to be 'awarded' a luxury cruise from Venice to the Greek islands, for her services as official artist to Scotland Yard. But also on the good ship Eurydice are her friends, Sir George and Lady Emily Colvedon, who know all about Miss S’s talent for tripping up wrongdoers. And by coincidence of course, there are a couple of well-known warring art experts, one of whom soon ends up dead.

This voyage is heading into stormy waters, but by the crook of her brolly Miss S untangles the truth and brings them all safely into harbor.

Serene amidst every kind of skullduggery, this eccentric English spinster steps in where Scotland Yard stumbles, armed with nothing more than her sketchpad and umbrella!
