It's 1947, and New York City is awaiting the construction of the new United Nations building, the FBI is actively pursuing Communists and Soviet spies as the Cold War begins to build, and homosexual men have even more reasons to hide who they are.

Uptight FBI Agent Arthur Mason is so deep in the closet he doesn't even realize he's in one. Clueless about his own sexuality, he's surprised at his reaction to both Hans Schmidt and his twin sister, Ada. Under pressure from work, Mason investigates Hans and his boarders, including the highly suspicious Hank Mannix, a known member of the Communist Party. Though Mason can't seem to locate Ada, he can't stop thinking about Hans and keeps going back to visit.

Hans Schmidt is a cross-dressing German immigrant running a boarding house for "a certain type of man," and he wants nothing to do with Agent Mason and his ill-fitting suits and bad haircut. Until he begins to see Mason more as a man and less as a government official.

Hans enjoys dressing as a woman from time to time, and once his feelings for Arthur begin to change, he realizes he needs to share his Ada persona if they are to have a future together.

Secrets on both sides must be revealed and cherished beliefs challenged if these two men are to find the love and happiness they deserve.

This story can be read on its own; however, characters from book one, Dublin Bay, play a prominent role as secondary characters, so it's recommended to read that first.
