I read a book, but forgot the name where the mm couple are married, and one of the MMC 1 finds the FMC in a bar and they have a affair.
The MMC 2 knows that his husband (MMC 1) is bi and sleeps with women.
MMC 2 later takes FMC with him to France to help solve a case.
MMC 1 parents are also very homophobic but rich.
Anyone have a guess?
Michelle: I’m almost positive it’s Sinfully Theirs by Serena Akeroyd. The characters are Mona, Zane (the bi MMC), and Jake. Jake finds out about the affair and blackmails Mona to go to France with him. The book is currently out of circulation.
