The House on Morgan Street is full of one-hundred years of secrets and lies that have come to the forefront after the death of the Abbott family matriarch. A scramble for hidden wealth ensues, and the bodies began to appear. Nothing is what it seems to be. Many people have come and gone from the mansion on Morgan Street, but it's what won't stay buried that brings a killer and his murderous greed to town.
The protagonist is Natalie, descended from a family of housemaids. She has created a safe, but very limited world for herself. When Lydia, the last living member of the Abbott family, comes home to Coventry, Minnesota for her mother's funeral, she has a secret that will take Natalie out of her small world and into a firestorm of secrets, lies, and murder.
Some of the stories of Natalie's family, along with observations of the past, are told through excerpts from journals and letters. The truth is dangerous and upends the lives of present-day Abbott family members and Natalie herself. Her lover James, the police chief, must balance his concern and love for Natalie with the pursuit of a dangerous and cunning villain. The romance between Natalie and James is one of rekindled love that makes them stronger together and yet more vulnerable. They fight to be together and to stay alive, as they struggle to catch a killer.
