The Mercyhurst Theatre Program presents a world premiere of Oh, Whistle, and I’ll Come to You, My Lad: An Erie Ghost Story. The play, by M.M. Barile, is based on a short story by M. R. James. At an Erie hotel in 1906, a college professor, his sister and a friend find a whistle on the shore and summon something hidden for generations. They quickly learn that skepticism is no defense against the supernatural. Tickets are $10 for adults, $7 for seniors, and $5 for students/youth (tickets half-price for Friday midnight show). To purchase tickets, visit miac.mercyhurst.edu or call the box office at 814-824-3000.
