Love, Betrayal and the Fallen Angel: A Tenet Gentlemen's Club Romance
Anne Shaw

Mr. Anthony Farnsworth is a guardian of the Tenet, a group of gentlemen investigating crimes committed by their peers. Anthony must wed to further his line as an heir to a barony, but he wants to marry a sensible miss with no illusions of love.
After Anthony rescues Sophia from drowning, tongues wag, and he has no choice but to propose marriage or risk tarnishing her reputation. Soon, their marriage of convenience becomes very inconvenient as passion and a deeper affection develops. When a mysterious attacker targets her sister, Sophia and Anthony work together to catch the deviant and, in the process, discover the key to their own happiness—each other.
