When one of the attackers is shot, Lacey rushes to his aid and learns that Thornton was attacking Horne’s house because he thinks Horne kidnapped his daughter Jane and is holding her hostage along with her maid Aimee. Lacey agrees to help Thornton locate Jane and Aimee, hoping some of his military connections will be beneficial.

Shortly after Lacey begins his less than discreet inquiries, funded by his former commander’s wife Louisa, who desperately wants her husband and Lacey to reconcile, Josiah Horne is found dead in his study. Aimee is found locked in an armoire, frightened half to death and completely unaware of the whereabouts of her mistress.

Lacey’s investigation turns up another missing girl and wonders if the two might be connected, or even worse, if it is the start of an epidemic of crime in London.

The Hanover Square Affair is the first of a new series set in Regency England. The time was very complex, both socially and politically, and is handled with ease complete with details that bring the period to life. While some of the characters are a bit unsavory, there are many interesting one who show promise to be expanded in the future.

Captain Lacey is a very complex man. He feels bitter about his physical condition and the way he was separated from the army and his best friend, yet he is grateful he was spared possible military penalties. He is still close to his former captain’s wife, but is not yet ready to let past pains go.

The plot is very intricate with the possibility of a madman in London snatching young girls. Both the wealthy side and the seamier side of London are portrayed, giving a lot of authenticity to the atmosphere. Lacey is an intrepid investigator and even though his results are sad for many, there is a glimmer of hope for Captain Lacey and a better future. While there is a lot for historical mystery fans to enjoy, the strong characters and the search to find Jane Thornton will intrigue even those who prefer mysteries set in contemporary times.
