Book excerpt: In his 1985 novel Partners in Crime, writer Rolando Hinojosa introduced homicide investigator Rafe Buenrostro, the first Chicano protagonist in one of the most enduring genres of modern literature. Since that time, Chicano writers have embraced the detective novel, successfully diversifying and refining a traditional Anglo American and British genre. The 21 whodunits of Hinojosa, Rudolfo Anaya, Lucha Corpi, Michael Nava and Manuel Ramos are closely studied in this groundbreaking work. The models, both contemporary and Romantic, of this relatively new Chicano genre are first discussed. Next come detailed analysis and reviews of such novels as Shaman Winter, Partners in Crime, Cactus Blood and 18 others, focusing on how each writer departs from contemporary detective genre formula, uniquely rendering a particular regional or cultural variation of what it means to be Chicano. It is this departure from the norm that defines these writings and distinguishes them from the Anglo American and British whodunit. Interviews with the writers conclude the work.
