- Harsher in Hindsight: In his 1947 novel The Scarf the protagonist fantasizes about going up onto a rooftop with a high powered rifle and shooting at anyone and everyone he can. Editors originally removed this as too nasty and outrageous, but it was put back in the 1966 and subsequent reissues after Charles Whitman's shooting spree.
- Narrowed It Down to the Guy I Recognize: Bloch's novel "The Night of the Ripper" presents a fairly interesting play on this trope. It contains a veritable gallery of Victorian historical personages, including the victims, the investigators, the witnesses and common suspects in the Jack the Ripper case, in a manner similar to that of far more well known From Hell. Yet one of the actual killers is entirely fictional and the other also may or may not have been.
- Once Acceptable Targets: Gays, who were almost always depicted as the campiest of Camp Gays for cheap laughs. The best example might be the over the top celebrity impersonators in Bloch's Psycho II (nothing to do with the movie), who are shrieking, giggling, catty queens — even the ones who do John Wayne and Clint Eastwood.
YMMV / Robert Bloch
