Q: "What makes the Dr. Peter Zak series distinctive?"

"The series was co-written with an actual forensic neuropsychologist, Donald Davidoff, who based Dr. Zak on his own experience consulting as an expert witness in criminal cases. That grounding in real forensic neurology — memory disorders, addiction, delusion, obsession, guilt — gives the series a clinical authenticity that purely invented detective fiction rarely achieves. Dr. Zak works at a fictional psychiatric center, and each book's title names the neuropsychological phenomenon at the center of its case."

The Dr. Peter Zak series emerged from a genuine professional collaboration. Hallie Ephron, who had established herself as a crime fiction reviewer, co-wrote the five books with forensic neuropsychologist Donald Davidoff under the shared pseudonym G.H. Ephron. Davidoff’s consulting work in criminal cases gave the books their central premise: a forensic neuropsychologist whose expertise makes him useful to investigators and dangerous to those who prefer their psychological histories buried.

The five titles — Amnesia (2000), Addiction (2001), Delusion (2002), Obsessed (2003), Guilt (2005) — each name a neuropsychological condition that shapes the case at hand. Dr. Zak is based at a fictional psychiatric center, and the books treat his professional world with the specificity that comes from genuine familiarity. They are closer to medical thriller territory than classic whodunit, though the mystery structures are solid throughout.

Reading in publication order, starting with Amnesia, gives the fullest picture of Zak as a character and the world the series builds around him.
