Recommended Reading Order

The best way to read the Alexander Gregory series is in publication order. Because Dr. Gregory's personal character arc and psychological struggles develop continuously across the books, reading them in sequence ensures you do not miss his evolution or encounter spoilers for earlier cases.

  1. Impostor (2019) – Set in a remote Irish village in County Mayo.
  2. Hysteria (2019) – Set in Paris during the chaos of Fashion Week.
  3. Bedlam (2020) – Set inside a sinister psychiatric facility in New York.
  4. Mania (2022) – Set in the atmospheric landscape of the English Lake District.
  5. Panic (2024) – Set in a peaceful Cornish coastal village.
  6. Amnesia (2024) – Set in London.
  7. Obsession (Expected 2026) – The seventh installment in the series.

The DCI Ryan Shared Universe and Crossovers

Dr. Alexander Gregory is part of a larger literary universe crafted by L.J. Ross. Before receiving his own dedicated spin-off series, Dr. Gregory made crucial appearances as a supporting character alongside DCI Ryan in Ross's landmark police procedural series. If you want a complete picture of his character, you can read these DCI Ryan books before starting Impostor:

  • High Force (DCI Ryan Book 5, 2017) – Features Dr. Gregory's first appearance helping the team.
  • The Moor (DCI Ryan Book 12, 2019) – Further builds his connection to the broader universe immediately prior to his spin-off debut.

How to Start Reading

If you prefer to focus solely on the psychological thrillers, start directly with Impostor. The book establishes Gregory's background as an elite forensic psychologist and criminal profiler who has recently retreated from London following a high-profile professional scandal. If you are a fan of Ross's broader universe, starting with the DCI Ryan novels High Force and The Moor provides excellent background context on Gregory's clinical expertise and professional relationships before his solo journey begins.
