'I crave for mental exaltation. That is why I have chosen my own particular profession, or rather created it, for I am the only one in the world.' Mary Morstan receives a large pearl through the post once a year without any clue as to the sender. When her intriguing correspondent requests a meeting, Holmes and Watson take on the case. Together the trio race through London to uncover the secrets of the Sholto family, who hold the key to uncovering the whereabouts of Mary's father and the existence of a treasure stemming from a crime committed years ago in India. The Sign of the Four has been a crucial part of the Sherlock Holmes canon since its first publication in 1890. It explores theft, betrayal, and murder in the larger context of the British Empire at a time of national upheaval, and the novel's flashbacks to India during the 'Mutiny' and its aftermath call into question the consequences of that imperial venture. Caroline Reitz's new introduction and notes draws attention to some often-overlooked context of the story, such as its original publication in Lippincott's Monthly Magazine, its representation of imperial violence, and changing gender roles.

In Detecting the Nation Reitz argues that detective fiction was essential both to public acceptance of the newly organized police force in early Victorian Britain and to acclimating the population to the larger venture of the British Empire. In doing so, Reitz challenges literary-historical assumptions that detective fiction is a minor domestic genre that reinforces a distinction between metropolitan center and imperial periphery. Rather, Reitz argues, nineteenth-century detective fiction helped transform the concept of an island kingdom to that of a sprawling empire; detective fiction placed imperialism at the center of English identity by recasting what had been the suspiciously un-English figure of the turn-of-the-century detective as the very embodiment of both English principles and imperial authority. She supports this claim through reading such masters of the genre as Godwin, Dickens, Collins, and Doyle in relation to narratives of crime and empire such as James Mill's History of British India, narratives about Thuggee, and selected writings of Kipling and Buchan. Detective fiction and writings more specifically related to the imperial project, such as political tracts and adventure stories, were inextricably interrelated during this time.
