Tonight on BBC3 at 7pm, is the frightfully spiffing episode of Doctor Who, The Unicorn and the Wasp, where the Doctor and Donna meet Agatha Christie.
Also tonight but on BBC4:
8.30pm The Book Quiz with one of the panellists (contestants?) being Mark Billingham author of the DI Tom Thorne series.
10.00pm Spiral. A repeat of the the first two episodes from Season 1 of the classy French crime drama.
The Book Quiz is repeated tomorrow and Thursday. Also on Thursday at 9pm on BBC4 is a repeat of New Town (aka Purves and Pekkala).
