A Man Downstairs by Nicole Lundrigan

What if the childhood you remember isn't really what happened at all?
"A gripping story of troubled relationships, mental illness and buried secrets with a murder at its heart. . . . Clever, twisty and chilling." —Shari Lapena, #1 bestselling author of Everyone Here is Lying
From the acclaimed author of An Unthinkable Thing and Hideaway, a breath-stopping novel of suspense about a woman tormented by memories of the past and threatened by long-held secrets in the present.
Molly Wynters has moved back to her small hometown to care for her father, recently felled by a stroke and no longer able to communicate. She is ready to make a fresh start with her son after her divorce, but is haunted by both old events and new realities in her childhood home.
What Molly recalls of her young life with her father is full of love and care, even though a violent trauma defined her childhood: when she was a young girl, she witnessed her mother's murder, and her testimony – "There was a man downstairs" – sent a teenager to prison. This tragic episode is still very much alive in the culture of the town, and the more Molly remembers, the more she fears that what she said on the stand all those years ago might not have been the whole truth.
After Molly, a trained therapist, volunteers for a local helpline, the threats begin. At first they seem random, but soon Molly realizes that she is a target, and even those closest to her seem suspicious, especially as unsuspected links between them emerge. More than one life was destroyed on that horrific long-ago day, and now someone intends to hold Molly accountable.
With its gripping descent into the shadowy corners of the human psyche A Man Downstairs is both an edge-of-your-seat thrill ride and a masterful exploration of the fragile nature of memory.
