MARQUETTE, Mich.— Auditions for Northern Michigan University’s production of The Mousetrap will be held at 6 p.m. Friday and Saturday, Jan. 15-16, with callbacks at noon on Sunday. The Agatha Christie murder mystery will be staged at Forest Roberts Theatre April 14-17. Director Paul Truckey requests that prospective actors prepare a one-minute, upbeat monologue for the auditions and also review the script and character roles for a possible callback. The Mousetrapopened in the West End of London in 1952 and has been performed continually since then, with more than 23,000 performances. It is the story of young couple Mollie and Giles Ralston, who have started up a new hotel in the converted Monkswell Manor. A snowstorm confines them to the manor with four guests and an additional traveler who ran his car into a snowdrift. When a murder of one of the guests occurs, suspicion and blame consumes the remaining guests and owners. For more information, call 227-2553.
