San Francisco, 1952. Detective Evander “Andy” Mills has started a new life for himself as a private detective, but his business hasn’t exactly taken off. It turns out that word spreads fast when you have a bad reputation, and no one in the queer community trusts him enough to ask an ex-cop for help. When James, an old flame from the war who had mysteriously disappeared, arrives in his offices above the Ruby, Andy wants to kick him out. But the job seems to be a simple case of blackmail, and Andy’s debts are piling up. He agrees to investigate, despite everything it stirs up. The case will take him back to the shadowy, closeted world of the Navy, and then out into the gay bars of the city, where the past rises up to meet him, like the swell of the ocean under a warship.

Lavender House, 1952: the family seat of recently deceased matriarch Irene Lamontaine, head of the famous Lamontaine soap empire. Irene’s recipes for her signature scents are a well-guarded secret, but it's not the only one behind these gates. This estate offers a unique freedom, where none of the residents or staff hide who they are. But to keep their secret, they've needed to keep others out. And now they're worried they're keeping a murderer in. Irene’s widow hires Evander Mills to uncover the truth behind her mysterious death. Andy, recently fired from the San Francisco police after being caught in a raid on a gay bar, is happy to accept. However, he quickly finds himself a pawn in a family game of old money, subterfuge and jealousy --- and Irene’s death is only the beginning.
