The Amazing Mrs. Pollifax

Audible Audiobook (Recorded Books May 16, 2011)

Emily Pollifax is one of a precious few gray-haired female sleuths who solve their cases through unflagging determination, moral courage and wisdom that comes with age. In The Amazing Mrs. Pollifax, Emily answers the call of that "nice Mr. Carstairs" to go to Istanbul as a courier and search for a missing agent.
