Typically the sensation novel focused on shocking subject matter including adultery, robbery, disguise, revenge, kidnapping, insanity,
bigamy,
forgery, seduction and murder. It distinguished itself from other contemporary genres, including the
Gothic novel, by setting these themes in ordinary, familiar and often domestic settings, thereby undermining the common
Victorian-era assumption that sensational events were something foreign and divorced from comfortable middle-class life.
W. S. Gilbert satirised these works in his 1871
comic opera A Sensation Novel. For
Anthony Trollope, however, the best novels should be "at the same time realistic and sensational...and both in the highest degree". When sensation novels burst upon a quiescent England these novels became immediate best sellers, surpassing all previous book sales records. However, highbrow critics writing in academic journals of the day decried the phenomenon and criticized its practitioners (and readers) in the harshest terms;
John Ruskin perhaps providing the most thoughtful criticism in his 'Fiction – Fair and Foul'. Some scholars speculate that the notoriety of the genre may have contributed to its popularity.
Henry Longueville Mansel from the
Quarterly described the sensation novel as "extremely provocative of that sensation in the palate and throat which is a premonitory symptom of nausea". ==Notable examples==
