On the plane to London, Mrs. Blossom’s stopping point on the way to Paris to board a river cruise, a handsome stranger takes her under his wing. And when they land in London, he sticks close to her, even helping her book into a hotel for the night.

A day later, she’s arrived in Paris but her new-found friend has been murdered. And another strange man seems to be everywhere she goes — including showing up as a passenger on her cruise boat.

Mrs. Blossom has a lot of questions, but she’s also got investigative instincts that help keep her safe and figure out what’s going on.
