The Stranger in Her House Summary: A Mother, a Daughter, and a Killer
Warning: This section reveals the entire plot, including the ending.
Connie has built a careful life around caring for her mother, Gwen, who is fading from vascular dementia.
The two live in a cottage in Avringstone, where Connie keeps a close eye on anyone who comes near.
Her vigilance cracks when Paul Michael appears, claiming to be from a charity called Help for Homes, offering free gutter cleaning. Gwen is charmed. Connie is not.
Paul inserts himself deeper. He runs errands, repairs a shed, and takes Gwen on an unannounced trip to Clacton-on-Sea.
Connie, believing her mother has been kidnapped, calls the police. But Paul counters that Connie has been making unwanted romantic advances.
The accusation sticks, and Connie’s credibility crumbles.

Connie is forced to leave the village for several weeks, supposedly for a wedding planning job in Italy.
In truth, her name is Rachel Evans, and she is serving a short prison sentence for credit card fraud. Connie is not Gwen’s daughter.
She is a con-woman who targeted Gwen for her property. While Connie is away, Paul marries Gwen. When Connie returns, Gwen is dead—listed as an accidental fall down the stairs.
Paul inherits the house, the bank accounts, and buries Gwen in an unmarked grave far from her late husband.
Connie investigates and uncovers a pattern. Paul is a serial predator who marries women with dementia, drugs them with Omixinol to worsen their confusion, kills them, and cuts out their tongues as trophies.
He believes these women are liars. He has done this before, with victims across multiple counties. When neighbour Walter tries to help Connie send evidence to the police, Paul murders him.
Paul kidnaps Connie and throws her from a railway bridge into the path of an oncoming train. She survives but is left with life-altering injuries.
Paul is eventually arrested after his fifth known wife, Fran Brown, survives long enough for a toxicology report to prove drugging. He pleads guilty to multiple murders and the attempted murder of Connie.
Connie believes she can finally claim Gwen’s estate through the original will.
She entrusts that will to Meredith Harper, Gwen’s long-lost second cousin.
But Meredith has held a lifelong grudge against Gwen, who married the man Meredith once loved. From prison, Paul sent Meredith evidence of Connie’s criminal past.
Working together, they strip Connie of all inheritance. Meredith takes the entire estate and embarks on a world cruise, while Connie is left penniless and facing prison again for shoplifting.
