Borachio, Conrad and Watchmen, Act III, scene iii, 1795
Excerpt for the scene summary: Suddenly, the watchmen are interrupted by the entrance of Don John’s associates, Borachio and Conrad. Borachio, who does not see the watchmen, informs Conrad about what has happened this night. Acting on the plan he developed with Don John, Borachio made love to Margaret, Hero’s waiting maid, at the window of Hero’s room, with Margaret dressed in Hero’s clothing. Don Pedro and Claudio, who were hiding nearby with Don John, saw the whole thing and are now convinced that Hero has been disloyal to Claudio. Claudio, feeling heartbroken and betrayed, has vowed to take revenge upon Hero by publicly humiliating her at the wedding ceremony the next day. The watchmen, who have quietly listened to this whole secretive exchange, now reveal themselves and arrest Borachio and Conrade for “lechery,” by which they mean treachery. They haul them away to Dogberry and Verges for questioning.
