At first glance, Linda McElroy looked to be another ordinary house cleaner. 
Sixty-four years old, overweight and with glasses, she had settled into an anonymous life in Pulaski, Tennessee. 
“She blended into the community,” forensic psychologist Paula Orange said. “Her employers all said the same thing about her. That she was a delight. Hard-working, friendly, and trustworthy.”
McElroy had remained in small, rural town of Pulaski for over thirty-five years. The reputation she had earned was hard-won.
No one knew about her previous life. 
She was a convicted murderer. 
But now she was for all intents and purposes, a respected member of the community. A wife, mother and now grandmother to eight grandchildren. 
Unassuming and harmless. 
But the past thirty-five years had to have been tortuous ones for McElroy. Any unexpected knock on the door must have sent her heart racing. Any police siren in the distance must have sent her on edge. 
Could this be the day?
The day when the authorities finally catch up with her. 
In 2007, they finally did.
