A NEW Classic Mystery

In 1926 Agatha Christie mysteriously disappeared. Ten days later, the 37-year-old wife and mother who dabbled in detective fiction was found at a posh seaside resort having checked in under the name of her husband’s mistress. Agatha Christie walked out of that hotel ready to become the icon we regard her as today, but why did she disappear? Shifting back and forth in time, and with a little help from Mystery’s favorite characters, Heidi Armbruster’s classic new comedy shows Agatha as she’s never been seen before. While attending a convention for mystery aficionados at Agatha Christie’s homestead, Lucy puts together clues that lead her to the truth of her Patron Saint Agatha’s mysterious eleven-day vanishing. Sometimes a woman needs to disappear in order to find herself.

Heidi has been working on this play in Dorset Theatre Festival’s Women Artists Writing Group since 2015. We are so proud to have the opportunity to produce the World Premiere before Mrs. Christie goes off to future productions across the country.
