Clarendon Estate - The Sinclair Society Series, #3

Juliet Sinclair must unmask a murderer before her own false identity is revealed...  Clarendon Estate, the country home of Sir Horace and Lady Celia Leith, has been a refuge for Juliet Sinclair after the traumatic events of Bath.  It may also be the home of a murderer.  All signs point to a significant connection between Sir Horace and Juliet's brother, and the more she investigates, the stronger her belief that the man may be the mysterious H she is searching for.
But revealing a murderer has consequences Juliet hadn't expected. In continuing her ruse of servitude, Juliet finds herself forming a close bond with Lady Leith as they thwart the designs of Sir Horace's domineering mother, a woman who will do all she can to keep control of the household. Can Juliet condemn her new friend to a life with such a woman as her only family? Time is running short. A house party is set to descend on Clarendon, bringing with it the threat of more than one person who may reveal Juliet's true identity and destroy her careful plans to keep her name above scandal.
But the truth is closer than she realizes...
