The Nether, a daring examination of moral responsibility in virtual worlds, opens with a familiar interrogation scene given a technological twist. As Detective Morris, an investigator of the Nether's online offerings, questions Mr. Sims about his activities in a role-playing realm so realistic it could be life, she finds herself on unexpectedly slippery ground. Sims argues for the freedom to explore even the most deviant corners of our imagination. Morris holds that we cannot flesh out our malign fantasies without consequence. Their clash of wills leads to a consequence neither could have imagined. Suspenseful, ingeniously constructed, and fiercely intelligent, Haley's play forces us to confront deeply disturbing questions about the boundaries of reality.
