Since her mother's murder four years ago, Lady Jillian Daventry has immersed herself in the study of criminology with the intent of uncovering the facts behind her mother's death. Jillian possesses an eye for detail that serves her well and has a prominent Bow Street runner confidentially contacting her regarding his most puzzling cases. After her fiancé jilts her for working in crime, she conceals her efforts from her family and society. Her family wants the scandal to fade into distant memory, so Jillian and her sister can make advantageous marriages. But Jillian can't let the past go until she can find her mother's true killer.

Connor Monroe, a former street urchin, transforms himself into a successful businessman. His harrowing and abusive childhood and the tragedy of his brother's death gave him a powerful motivation to succeed and to never be at anyone's mercy. As he betters himself, Connor has made a new family consisting of people who aided him. Now those people are dying mysteriously. Unable to supply Bow Street with motives for the deaths, they look for the simplest solution. Connor rejects their conclusions and barters a tentative agreement with a Bow Street consultant, Lady Jillian Daventry.

Upon meeting, Jillian and Connor feel a powerful attraction that grows as they work together to uncover the killer. In the middle of a murder investigation, a romance between a society lady and an unsuitable suitor is impossible. Or is it?

Talented newcomer Kimberly Logan cements her place as an author to watch in her second novel, SINS OF MIDNIGHT, the first in a trilogy. She combines romance and mystery equally with sufficient red herrings to keep readers off balance and guessing. One killer is exposed, while another is left in the background awaiting her next tale.
