Love, jealousy, lust, lies, trickery, murder and trading sex for a favor. Though it's more than 100 years older than "Desperate Housewives," Puccini's TOSCA could practically stand in for an episode. The 19th-century Italian opera takes the stage at the Atlanta Civic Center MAY 18. Although we all know that by the end of an opera somebody must die, be prepared: Tosca takes place in the course of a single day, during which the four main characters meet a violent end. $25-$125. May 18, 20, 8 p.m.; May 21, 3 p.m. 395 Piedmont Ave. 404-881-8885. www.atlantaopera.org.
