A Palm for Mrs. Pollifax by Dorothy Gilman, Barbara Rosenblat

Settling into her later life isn't something that Mrs. Pollifax wants to do. Yes, she's got full days with neighbors, learning judo and yoga, and attending her garden club. But it's all so distressingly... normal. So when she gets a letter and then shortly after a phone call, she is ready for an adventure. 

Mr.  Carstairs is sending her to Switzerland. To a health spa, no less. But why? Because somebody at that spa is connected to a rash of plutonium thefts. And they are close to enough plutonium to make an atom bomb and that would be a very bad thing for the world.

At the health spa are a number of interesting people including Robin Burke-Jones, a young man who dresses in the loud clothes of the day but seems to be at the spa for reasons of his own; Hafez, a boy who is just a little too anxious to make Emily his friend; a man in a wheelchair who is interested in the goings-on across the hall (Hafez's room); a young woman who has caught Robin's interest and goes hiking early every morning; Marcel, a waiter who might be more than he appears.

Even though Interpol is also on the scene, Emily is in more danger than she has been in many past books. 

A wonderful listen made even better by narrator Barbara Rosenblat. A little overwrought and maybe didn't age completely well but good for a day of data entry.
