Mistresses and Mayhem — Allison Rushby

Triplets--estranged since birth--are thrust together in glittering 1926 London to fight for their inheritance, only to learn they can't trust anyone--least of all each other.

Disgusted with Charles and his cruel tricks, the girls finally agree to band together in hopes of finding another way to win the fortune from Charles. However, when Thalia runs into trouble at a party and one of her sisters has her sent away, it divides the girls even more fiercely than before. Only a chance encounter which reveals a shocking truth about their mother might be able to bring them together to defeat Charles--once and for all.
