The fourth and final volume of the author’s monumental reference on 20th-century stage crime begins chronologically with the 1975 John Kander/Fred Ebb/Bob Fosse musical Chicago and ends with Moisés Kaufman’s The Laramie Project (2000). Discussed along the way are modern classics (David Mamet’s American Buffalo, Sam Shepard’s Buried Child), adaptations of print novels (three versions of The Hound of the Baskervilles, two of Dracula, A Murder Is Announced, No Orchids for Miss Blandish, The Little Sister, The Talented Mr. Ripley, To Kill a Mockingbird, Jane Eyre), and numerous offbeat or obscure oddities that have managed to get an English-language production. Represented are renowned mainstream playwrights (David Rabe, Terence Ratigan, Tom Stoppard, David Henry Huang, Romulus Linney, Tennessee Williams), and others best known for mystery fiction (James Yaffe, Simon Brett, Francis Durbridge, Ira Levin, David Stuart Davies). Entries provide exhaustive descriptions and plot summaries, stage histories, notes on the playwrights and authors of source material, and quotes from reviews. Appendices on poison, the courtroom, death row, children in peril, and one-acts update information from the previous volumes. This is one of the key secondary sources of the young century, and I hope some awards-giving body will recognize it.
