Mr. Pottermack’s Oversight is a forensic detective drama based on Freeman’s 1930 inverted mystery featuring his celebrated sleuth Dr. Thorndyke.
The narrative centers on Mr. Pottermack, whose outwardly comfortable life is upended by a blackmailer’s threats. As events spiral from crime to cover‑up and scientific detection, the meticulous Dr. Thorndyke’s forensic acumen ultimately drives the investigation forward.
