No swindle here: a professional cast, a polished design, an 11-player orchestra, a hot show just a few seasons removed from Broadway, a reasonable ticket price, all in comfortably posh surroundings at Covington's Carnegie Center. For a musical about con artists, 'Dirty Rotten Scoundrels' is surprisingly on the level.   

It's back ... that musical with the mouthful name that kicked up so much excitement last summer at the 2008 Cincinnati Fringe Festival. Ensemble Theater of Cincinnati bills Richard Oberacker's and Robert Taylor's no-plot, no-dialogue, five-person fantasia on parenting production as a premiere, and considering the changes that's close to true.
