Longtime musical theatre collaborators Stephen Sondheim and George Furth, who together created the landmark musical Company, have joined forces again to create a compellingly original thriller - Mr. Sondheim's first nonmusical play, Getting Away With Murder unfolds on a stormy night on Manhattan's Upper West Side at a group. therapy session.  The patients arrive only to find that their faithful, Pulitzer Prize-winning psychiatrist is missing.  What unfolds is a classic whodunit in the tradition of Sleuth and The Mousetrap that harkens back to Sondheim's screenplay collaboration with Anthony Perkins on the cult film The Last Of Sheila.  Getting Away With Murder, originally produced at San Diego's Old Globe Theatre, was produced on Broadway in 1996.
