A man who thinks he's seen the ghost of his dead wife goes to a shrink to talk about it. In a few scenes, over the next few weeks, the uncomfortable secrets of both are revealed. In a year when musicals dominated Broadway, Conor McPherson's Dublin-set ghost story was that rare treat: a pitch-perfect 90 minutes of tense psychological drama. Robert Falls's understated production, starring Oliver Platt and Brian F. O'Byrne, bided its time until a frisson at the end that makes my own Top 10 list of great Broadway moments.
