Three new works by Pulitzer Prize-winning author John Patrick Shanley, one of our country's most politically current and theatrically elastic playwrights. In Dirty Story, a couple of sadomasochistic writers fight over rights to their New York City loft. In this sexy satire of the Israeli-Palestinian conflict that is ''astonishing,'' says Tony Kushner, ''the analysis of the Middle East in this play is dead on, exactly perfectly pitched. ''In his dark comedy Where's My Money?, Shanley takes on marriage, infidelity, and divorce lawyers in a play that is ''so harsh, it's funny - terrifying, but funny'' (The New York Times).And in his Sailor's Song, love becomes an act of courage, in a seaside romance about the certainty of death, the brevity of youth, and the importance of now.
