The Elusive Mrs. Pollifax (Mrs. Pollifax, #3)
by Dorothy Gilman

5 out of 5 stars

Mrs. Pollifax is recruited to deliver some passports to the Underground Resistance in Communist Bulgaria. It seems like a straightforward courier job, but nothing is ever straightforward with Mrs. Pollifax. She befriends a group of young hippie tourists, and when one of them is arrested for espionage, Mrs. Pollifax suspects that something else is going on.
