If Watson is the cliché version of the Victorian doctor, bumbling but reliable, predictable, and unambiguously heterosexual, then Holmes is a genius of deductive science and criminological diagnosis. There is a sense in which this genius is psychologically abnormal in the stories; Holmes is first encountered in a medical environment, the chemical laboratory at Bart’s, a setting which is more immediately suggestive of the mad scientist than the detective. His medical knowledge is described as “desultory and eccentric” (16). He, Sherlock, beats the cadavers in the mortuary with a walking stick “to verify how far bruises might be produced after death” and enthusiastically extracts his own blood for use in chemical experiments (17).

Christopher Redmond observes that the modern-day pilgrimages taken by Holmes fans in London encompass not only the iconic reconstruction of the sitting rooms at 221B Baker Street, but frequently extend to the streets and locations where various events take place in the stories (Stashower).
