A Play of Treachery by Margaret Frazer

In this book we see Joliffe in France while he's being trained as a spy. Although I generally enjoy the rest of Joliffe's troupe, the mysteries surrounding their travels were getting a bit repetitive. In addition to his training, Joliffe is working as a spy in Rouen, the site where England's power in France is massed. He must solve a murder, gets a bit of romance, and uncovers personal secrets that have bearing on affairs of state. This story helps connect the Joliffe we meet early in the Dame Frevisse books to the one who appears in her later stories.
