Flying Too High by Kerry Greenwood (1990)

In Phryne Fisher's second adventure,where she has already established herself as a mystery solver in the high society of 20's Australia, she is asked to prevent a hot tempered son from killing his father. The father actually does get killed, and now she tries to prove the son was innocent. Meanwhile a young girl is kidnapped, so Phryne promises to help find the child and does so in the wildest way imaginable. While doing all this sleuthing and problem solving, she shows off her skills as a pilot and dare devil, gaining her new respect, though scaring her poor assistant Dot half to death. The planes end up playing a role in her solution. In the first book we learned how she came to Australia. In this one she buys a house and gets established with Dot and Mr. & Mrs. Butler - cook and maintainer of house and garden. Her one request is that her private life remain private, as she does enjoy her men. Just love her.

These are just scrumptious little books. I hope to get through a bunch of them. Only a few are available in audio, will have to check out the public library.
