Robert Marshall stands on the doorstep of a grand Regency house in Brighton, drawn by an inexplicable force to the home of Alessandra King, a woman he barely knows but finds irresistibly alluring. His decision to enter marks the beginning of a harrowing journey into psychological manipulation and obsession.

Robert's life spirals into chaos as Alessandra's hypnotic influence deepens. Her striking beauty and commanding presence ensnare him in a web of mental domination, pushing him to the brink of sanity. Despite his growing awareness of her malevolent hold, Robert is consumed by a desperate need for her approval and affection.

Amidst this turmoil, Robert's old friend, Kathleen Ward, emerges as a beacon of support and rationality. A successful solicitor with her own history of emotional struggle, Kathleen sees through Alessandra's facade and understands the psychological damage being inflicted on Robert. Her attempts to reconnect with him and offer a lifeline are pivotal in his journey towards self-realisation.

As Robert's obsession reaches a fever pitch, he unravels deeper traumas from his past, particularly his troubled relationship with his mother. These buried memories resurface, providing insight into his vulnerability to Alessandra's manipulation.

The narrative builds to a tense climax as Kathleen uncovers evidence of Alessandra's abusive behaviour towards her employees, leading to a legal showdown that threatens to expose Alessandra and liberate Robert from her grasp. Confronted with the truth of his past and present, Robert must decide whether to succumb to the darkness or fight for his freedom and identity.

Lewis explores themes of obsession, trauma, and redemption, leaving readers questioning the boundaries of influence and the resilience of the human spirit.
