Murder in Moonlight by Mary Lancaster

A house of secrets, an impossible attraction

On a personal quest, Constance Silver, who runs Mayfair’s most exclusive brothel, has lied her way into Greenforth Manor, home of respectable and charismatic provincial banker, Walter Winsom. She feels quite safe from recognition until Solomon Grey joins the party.
Aloof and strangely exciting, Solomon is one of the wealthiest men in London, so what does he want with any of the small players gathered at Greenforth? More immediately, will he give Constance away? He saved her life once, with most disturbing effects on her, and she is still magnetically drawn to him. But he is one of the few men she cannot read or influence.
When they discover their host’s murdered body together, they have to overcome distrust of each other to investigate. Everyone in the house seems to have had both motive and opportunity to kill him, so Constance and Solomon must uncover many secrets and set a dangerous trap in order to reach the truth.
