The issue of loyalty and betrayal is dramatized through dialogue in the Governor-General's-Award-winning Three in the Back, Two in the Head, which appears to have been based on the assassination of Gerald Bull, the brilliant Canadian scientist who designed the first Star Wars system twenty years before Reagan announced his version. Bull ran afoul of the Pentagon and the CIA by his dealings with China, Chile, Yugoslavia, and Iraq. But Sherman's play is not a docudrama in any sense, for it merely uses some of the circumstances of the murdered scientist's career in order to concentrate on questions of personal and state morality as these circumscribe issues of loyalty and betrayal.
