Set in a creaky eighteenth‑century New England tavern called the Barnsley Inn, Murder Inn opens with a storm that forces a “Ghosts & Ghouls of New England” tour group to seek shelter inside. The inn, owned by the cantankerous Martha Talbot and tended by her son Jake, is rumored to be haunted by Marco, a knife‑throwing poltergeist that adds a spooky, tongue‑in‑cheek atmosphere. As the guests settle in, the lights flicker and a scream pierces the night—one of the tourists has been murdered. Panic erupts, and the eclectic cast—including the meddlesome Agnes Tate, the witty senior‑citizen duo Grace and Doris, and various other travelers—begin a frantic, comedic investigation. Accusations fly, alibis crumble, and secret motives surface, all while the legend of Marco looms in the background, providing both red herrings and moments of slapstick humor. The play balances the tension of a classic whodunit with rapid‑fire dialogue and physical comedy, keeping the audience guessing about the killer’s identity without ever revealing it in the summary. By the end, the mystery remains tantalizingly unresolved for the reader, inviting theatergoers to experience the full twists and laughs onstage.
