One of Charyn’s best-known protagonists is Isaac Sidel, a Jewish New York detective turned mayor, and the subject of ten crime novels, including Blue Eyes and The Good Policeman. Charyn’s brother, Harvey, a homicide detective with the NYPD, added authenticity to this popular series. Otto Penzler, founder of Mysterious Press, reissued the entire series in April, 2012, co-published by Open Road Media. The Sidel books are slated for development as an adult animated series, to be called Hard Apple.
