Joker/Harley: Criminal Sanity (2019-)

In Gotham City, the GCPD depends on the clinical expertise of Harley Quinn, a forensic psychiatrist who profiles the city's most violent offenders. Her work is defined by one failure: the unsolved murder of her roommate, a crime bearing the distinct signature of a figure known only as The Joker. Five years later, a new wave of meticulously staged killings forces her to reopen that cold case. As the evidence mounts, her professional detachment erodes, replaced by a singular fixation on the perpetrator's identity. The investigation now pulls her into the same moral darkness she is tasked with analyzing, blurring the distinction between hunter and prey. Her final report will be written in blood and ink.
