Salem's Pentacle Theatre returned to the stage this month with performances of murder mystery "The Mousetrap," which runs through Oct. 23.

The play, written by Agatha Christie, is set at the Monkswell Manor guesthouse, where employees and guests fall under suspicion after a local woman turns up murdered.

"A police detective, arriving on skis, interrogates everyone: the newlyweds running the guest house, an architect who seems better equipped to be a chef, a dissatisfied jurist who makes life miserable for all, a retired Army major, a spinster with a curious background, and a strange man with an unplaceable accent who claims his car overturned in a snowdrift. It soon becomes clear that the killer is among them, and the seven strangers grow increasingly suspicious of one another," the theatre said in a description of the play.

General admission tickets are $25, with a 50% discount for frontline health care workers. For more information or to buy tickets, visit the theatre's website.
