Indian Valley Theatre is preparing for its annual dinner theater next month. This year they will present Ken Ludwig’s murder-mystery “Postmortem.”

The show is based on the somewhat strange life of William Gillette, one of the most popular American actors of the early 20th century, who pioneered the role of Sherlock Holmes on the stage.

In IVT’s production of “Postmortem,” the cast of Gillette’s latest Broadway revival of “Sherlock Holmes” has assembled for a weekend of relaxation at his magnificent medieval castle on a bluff overlooking the Connecticut River.
