Had your fill of Nutcrackers? A winsome alternative this holiday is “Christmas at Pemberly” running through December 23 at the Marin Theater Company in Mill Valley. It’s a sequel to “Pride and Prejudice”, Jane Austen’s novel that keeps on giving birth to more novels, musicals and zombie versions. The plot focuses on the romantic travails of Mary, the youngest of the Bennet sisters. (She was the music nerd). Tickets $10-44.
