Dea Poirier

Dea Poirier writes psychological suspense and crime fiction, also publishing some earlier work as D. H. Poirier. The Marriage Counselor follows Adele, a therapist whose professional skill at recognizing troubled relationships offers little protection when her own husband disappears and evidence of a second life begins to surface. Bookouture issued The Marriage Counselor during 2023. Poirier builds the story around concealed motives, competing versions of a marriage, and the gap between a carefully managed public image and private knowledge. The domestic setting distinguishes it from her Calderwood Cove mysteries, beginning with Next Girl to Die, which use a small Maine town and a police investigation as their frame. Her other suspense novels include Find Me in the Dark and The Girls in the Fire. Across these books, Poirier often places a woman with professional responsibilities inside a mystery that also tests family loyalties. The Marriage Counselor turns that pattern inward by making the investigator’s most difficult case inseparable from her own home and reputation.
