The Notting Hill Mystery begins in London, where the wife of the sinister Baron R__ dies after drinking from a bottle of acid, apparently while sleepwalking in her husband’s home laboratory. It looks like an accident until insurance investigator Ralph Henderson learns that Baron R__ took out numerous life insurance policies on his wife. As Henderson investigates the case, he discovers not one, but three murders. Presented as Henderson’s evidential findings - diary entries, family letters, chemical analysis reports, interviews with witnesses, along with a crime scene map - the novel displays innovative techniques that would not become common features of detective fiction until the 1920s.
