The thriller about trust, greed, sisterhood, loyalty and a valuable stamp from the nation of Mauritius will feature DTF veteran Mary Bacon (Broadway's Rock 'n' Roll and Arcadia, Off-Broadway's Eccentricities of a Nightingale) as Mary; Mandy Siegfried (Rebeck's Our House Off-Broadway) as her half-sister, Jackie; Emmy Award winner Tom Pelphry ("The Guiding Light") as Dennis; the playwright-actor Keith Reddin as Philip; and Guy Boyd (Broadway's Sex and Longing, August: Osage County, Off-Broadway's Betty's Summer Vacation) as Sterling.

Ari Edelson (whose work includes developing new plays for the Old Vic Theatre's New Voices US/UK program) directs Mauritius at DTF's home at the Dorset Playhouse, in Dorset, VT.

Dina Janis, artistic director of DTF, said in a statement, "Building upon the success and acclaim of last year's new play premiere of The Novelist, Dorset Theatre Festival is thrilled to once again be presenting the work of renowned playwright Theresa Rebeck, a part-time resident of Dorset Hollow. Mauritius is a riveting thriller about time/place/inheritance and the world of philately."

Prolific screenwriter, novelist and playwright, Rebeck's work includes The Scene, Omnium Gatherum (co-writer), Our House, The Understudy, The Water's Edge, Spike Heels and more. Her new play, The Seminar, will get its world premiere on Broadway in the fall, starring Alan Rickman. She also created the new TV series "Smash," to premiere in early 2012 on NBC. The Emmy Award winner has also written for TV's "LA Law," "Law and Order," "Criminal Intent," "NYPD Blue" and "Brooklyn Bridge."
