Ladies of London’s High Society are known for their social graces and poise. Vivian Kirby boasts neither of these enviable qualities, though she does offer impressive conversation on chemical compositions. Unfortunately, it appears that not many men want a brilliant wife. So it is that Vivian finds kinship with a group of young women who embrace each other’s differences: The Blue Orchid Society. After an extended stay in China, Lord Benedict has returned transformed to his family’s estate, where an encounter with Vivian, whose scientific knowledge he once undermined, leaves him determined to make amends. He arranges to help forward her research—anonymously, of course. Through letters, Vivian establishes a warm friendship with her secret benefactor, even as she’s unexpectedly drawn into a murder investigation that forces her to work alongside Benedict to unearth the truth. Soon, Vivian fears she may be falling in love with two men, never suspecting that they are one and the same.
