Mrs. Blossom is a practical, devoted grandmother, and she has a knack for blending into the background, which was an asset during her days assisting private investigator Tess Monaghan. But when Mrs. Blossom finds a winning ticket in a parking lot, she is determined to see the world that sometimes feels as if it’s passing her by.

But when Mrs. Blossom booked her cruise through France on the MS Solitaire, she did not expect to meet Allan on her transatlantic flight, the first man who’s sparked something inside her since her beloved husband passed.

She also didn’t expect Allan to be found, dead, twenty-four hours later.

Now Mrs. Blossom doesn’t know who to trust on board the ship, especially when a mystifying man, Danny, keeps popping up around every corner, always present when things go awry. He claims that Allan was involved in the transport of a stolen piece of art, and he’s convinced that Mrs. Blossom knows more than she lets on.

Mrs. Blossom’s questions only increase as the cruise sails down the Seine. Why does it feel like she is being followed? Who was Allan, and why was he killed? Most alarmingly, why do these mysterious men keep flirting with her?
