Single and solitary Mallory, 28, has crafted a life in Chicago suburbia where she doesn't have to interact with many people. She works from home and her best friend lives in New York City. Her real passion is true crime, and she fills her time listening to podcasts and participating in forums, playing armchair detective about unsolved murders.
Enter Donovan. He moves in across the street and seems perfect: handsome, charming, considerate. Too good to be true? Mallory’s spidey senses have told her that if someone presents as perfect, they are hiding a dark secret. Despite this, Mallory and Donovan form an attraction and she can’t help but fall for him. While her heart is telling her one thing, her brain is screaming that Donovan has a secret. So Mallory tries to solve a real life mystery – to see if the man she’s falling in love with is actually a killer.
