Actors do love their dramas, and the members of the Causton Amateur Dramatic Society are no exception. Passionate love scenes, jealous rages? they?re better than a paycheck (not that anyone one in this production of Amadeus is getting one). But even the most theatrically minded must admit that murdering the leading man in full view of the audience is a bit over the top. Luckily, Inspector Tom Barnaby ? first seen in The Killings at Badger’s Drift — is in that audience, and he’s just the man to find the killer. With so many dramas playing out, there’s no shortage of suspects, including secret lovers and jealous understudies galore. Ms. Graham tweaks her collection of community-theater artistes and small-town drama queens with merciless delight until the curtain falls on the final page.
