"Detective Thomas, there’s no easy way to say this. We’ve brought Debbie in for questioning."

"You mean my sister Debbie? What are you talking about? You’ve arrested my sister?"

"Megan, she’s our prime suspect."

Detective Megan Thomas hoped that moving to Devon would mean a quiet life. Her years undercover in London left her broken and alone, unsure if she would ever recover. Slowly, she’s learning to work with a team and trust other people. But when her sister, Debbie, finds the body of local businessman Greg Porter, that peace is shattered. 

Porter’s wife and children don’t seem entirely grief-stricken, and his business dealings are not all they appear to be. So why are the police so determined to focus on Debbie? And why is she acting so suspiciously? When Megan learns what happened between Porter and Debbie, it threatens to tear the family apart and forces her to ask if her beloved sister could really have done something so terrible. 

Her boss won’t allow her anywhere near the case, leaving Megan on the sidelines. Caught between the job she loves and what she feels she must do, Megan finds herself faced with an impossible decision. She’s desperate to save her sister, but what if Debbie is lying? When a second body and a surprise confession takes the case into even muddier waters, Megan must decide where her loyalty lies - with her family or the truth. 

And whatever choice she makes, will she be able to live with herself?
