A fun historical spy story about two government agents in the 1920s. What sets this one apart, in addition to great period detail, are the characters.
Briers Allerdale is the more conventional hero, a player in the Great Game, accustomed to moving among other spies and agents and provocateurs and guns for hire across Europe. He's now back home in London for a new assignment. A dangerous known-anarchist woman has been spotted playing the role of a maidservant in the cozy domestic household of a public works planner. The home is not far from other juicier targets, and it will be Briers's job to try to locate her even-more-dangerous male partner, and figure out what their target might be. Not an unfamiliar job, but the one hitch is that the boarding house with a great view of the maid's front door accepts married couples only. In 1920's London, no actual female agent is available whom Briers's boss is willing to put at risk. So a different "wife" is being provided for his cover.
If Briers were in fact typical of his kind, he might be annoyed or disgusted to be paired with a man who cross-dresses as his pretend spouse. But Briers is gay, very self-aware, and not inexperienced, even to having had a lover once who liked skirts. He's not happy to be partnered with a guy whose main experience is linguistics and ciphers, but not because the man looks good in a frock.
Miles Siward has not had a lot of experience with the rougher side of intelligence work, but this isn't the first time he's worn silk stockings and heels for his government. What he hopes they don't realize, is how much he actually enjoys doing so. As Miles, he's brilliant but diffident and somewhat nervous, a small man with more brain than brawn. As Millie though - ah, as Millie she's sharper, stronger, a woman to be reckoned with. Millie lets Miles express himself in different and bolder ways. And Millie makes a very good field agent.
This is a fun romp in its plot, with action, disguise, and drama. Briers has some secrets he hasn't told anyone about his past encounters, which may or may not become a problem. Miles isn't used to physically chasing bad guys, but he's willing to try, even in heels. Add a great manservant, a brother who can't understand Miles one bit, co-workers who think anyone who will wear skirts may be untrustworthy, and a boardinghouse full of people who might see through Millie's disguise, to anarchists, guns and bombs. It's great fun.
It's also a sweet romance, slow to start, as each man feels out the other, in an era when being found out to be gay was punishable by prison and hard labor. Briers is protective, Miles is prickly and unsure. They strike both sparks and mistakes from each other. I thoroughly enjoyed the read, and would love to see these two work another case together.
