The owners of The Right Sort Marriage Bureau are back, and more determined than ever to bring love matches to the residents of Post-WWII London . . . so something as trivial as being dragged into a spy mission isn't going to stop them!

Sparks fly when an old friend comes to town . . .

London, 1947. After recent events have left the normally steadfast Iris Sparks thoroughly shaken, she's looking forward to some peace. With The Right Sort doing well, she and business partner Gwen Bainbridge are due a holiday. Until Iris's former boss enlists their help for a secret mission.

Iris, who left British intelligence after the war, is being recruited for her Cambridge connection to one Anthony Danforth. She hasn't seen Tony in almost ten years, yet she and Gwen must manipulate him into hiring their marriage service.

Tony's suspected of being a Soviet operative, and an undercover agent posing as his perfect match could discover the truth. Despite her reluctance at being dragged back into the world of espionage, Iris agrees. After all, Tony was once a very good friend. If he's innocent, she'll happily prove it. If not? Well, no one ever said being a spy was easy . . .
