Meet Mrs Blossom. . .

A widow who has never left the US
A grandmother with a knack for blending in
A lottery winner with an unexpected fortune

Determined to finally see the world, she's starting with a cruise along the Seine.

Just twenty-four hours into Mrs Blossom's trip, however, a man is dead, a precious artefact is missing, and a mysterious stranger is claiming her life is in danger. Surrounded by luxury food, quaint towns and people with staggeringly high net worths, she has no idea who she can trust.

But maybe blending into the background has its perks - whoever is responsible will never see this most unlikely of detectives coming.
