In June, DC will publish a companion one-shot to Kami Garcia, Mico Suayan, Mike Mayhew, and Jason Badower's Joker/Harley: Criminal Sanity. Joker/Harley: Criminal Sanity Secret Files #1 by Garcia and Ed Kurz, M.D. and featuring art by David Mack, Jason Badower and more, hits shelves on June 6. Cover art is by David Mack.
In Criminal Sanity, Harley Quinn is hunting two serial killers: "The Joker, a brutal psychopath who murdered her roommate and disappeared years ago, and the killer currently terrorizing Gotham City," reads DC''s description. "Throughout the acclaimed series, Garcia has been consulting forensic psychiatrist and behavior analyst Edward Kurz, M.D., to ensure the accuracy of the story and of Harley’s methodology."
Secret Files #1 adds in "pieces of the puzzle on Harley’s investigation board and steal a glimpse into John Kelly’s high school notebook—a book he still carries today."
“I had worked on an X-Files book, and my friend, Dr. Ed Kurz, was one of my consultants,” explained Garcia in an announcement. “He’s a real forensic psychiatrist profiler. Harley Quinn basically has a very similar job. Dr. Kurz works in a facility for the criminally insane. I wanted to play with the idea of Harley having that training and working as a behavior analyst and a profiler."
Kurz has been a consultant on the main Criminal Sanity series, and Newsarama interviewed him and Garcia about the series in 2019.
“We profiled Joker as if he were a real person. I wanted to write a very accurate procedural. I wanted people to make sure their doors were locked after they read the issue. To really feel like he could be out there.”
Joker/Harley Criminal Sanity Secret Files #1, retailing for $5.99, carries an Ages 17+ content descriptor and is printed in DC’s Prestige Plus format (approx. 8.5” x 10.875”).
According to DC, "Dr. Kurz’s work is spotlighted as we reveal secrets from Harley’s past, hidden details of crime scenes, and a real-life profile of The Joker that has driven the progression of his murders in the story!"
“I know an inappropriate amount about serials killers for someone who’s not a serial killer or a psychiatrist,” offered Garcia.
