Bill James’ dark comedy “Snatched” is a biting satire that takes place behind the scenes at the Hulliborn Regional Museum and Gallery. The new director George Lepage, is hoping for a brief but successful stay. But when a crazy former employee starts a ruckus in the Folk Department and three recently acquired absurdly costly paintings with questionable provenance are taken, mayhem results. The security and wisdom of the museum are questioned and “Flounce” Butler-Minton’s legacy is very much in evidence.
