Penny For Your Secrets by Anna Lee Huber

In this third installment in the Verity Kent series, Verity and Sydney Kent are pulled into murder mystery when Verity's friend, Ada, is accused of killing her unaffectionate aristocratic husband. A few days later they are asked to investigate another murder, this time the sister of one of Verity's spy buddies. As Verity and Sydney follow clues they continue to work on their relationship and deal with the ghosts of their past. 

This is a pretty fun series. There is a lot of chemistry between Verity and Sydney and their on again/off again passion leads to good sexual tension. That being said, all their marital exploits are completely off screen. The mystery elements are well crafted, and the portrayal of the roaring twenties in post war Europe is interesting. I only wish they had a different reader narrating the book. I don't know why they chose her.  Her accent and character voices are ok, but she totally doesn't understand phrasing. Oh well.  I am more tolerant of bad readers than some people so I will probably end up listening to more in the series. (2019, 336p)
