Secrets on the Côte d’Azur might be my favorite Mydworth Mystery so far. Harry and Kat are on a work/pleasure trip to the French Riviera. Harry has to do a bit of government work and then they can enjoy themselves. Until Aunt Lavinia introduces them to a friend in need of help. Percy Porter, an English pickle baron, is being blackmailed over his relationship with a younger French cabaret singer.

The mystery is good. Harry and Kat do a lot asking questions and tailing people. I appreciated the twist in the whodunnit. The characters in this one were great. Harry and Kat are their usual charming selves, but we meet some new people who are entertaining and add a lot to the story.
