November 2-4 1972 at Earl of March Secondary School as part of Season #4 1972-1973
| Written by Agatha Christie |
After a local woman is murdered, the guests and staff at Monkswell Manor find themselves stranded during a snowstorm. It soon becomes clear that the killer is among them, and the seven strangers grow increasingly suspicious of one another. A police detective, arriving on skis, interrogates the suspects: the newlyweds running the house; a spinster with a curious background; an architect who seems better equipped to be a chef; a retired Army major; a strange little man who claims his car has overturned in a drift; and a jurist who makes life miserable for everyone. When a second murder takes place, tensions and fears escalate. This record-breaking murder mystery features a brilliant surprise finish from Dame Agatha Christie, the foremost mystery writer of her time.
