"Whenever a new Laura Lippman comes out there is reason to celebrate!" --Louise Penny

Highly acclaimed New York Times bestselling author Laura Lippman returns with an irresistible mystery featuring Muriel Blossom, a former private investigator and middle-aged widow whose vacation on a Parisian river cruise turns into a deadly international mystery...that only she can solve.

Mrs. Blossom has a knack for blending into the background, which was an asset during her days assisting private investigator Tess Monaghan. But when she finds a winning lottery ticket in a parking lot, everything changes. She is determined to see the world that she sometimes feels is passing her by.

When Mrs. Blossom booked her cruise through France on the MS Solitaire, she did not expect to meet Allan on her transatlantic flight. He is 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 in Paris, a city he wasn't supposed to be in.

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 is convinced that Allan was transporting a stolen piece of art, and Mrs. Blossom knows more than she lets on, regarding both the artifact and Allan's death.

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?
