Thin Ice

Series 10 - Episode 3 Thin Ice



London, 1814: a vast mud-caked creature wails in anguish down by the Thames… No, it’s not Tom Hardy returning unexpectedly early as James Keziah Delaney in Taboo. We are in the exact same year and setting, but Doctor Who delivers a far less squalid depiction of Regency London – its street urchins are quite well turned out.

The Doctor and Bill arrive at the last of the great frost fairs on the Thames, where revellers and children have been vanishing under the ice. There are monsters at large – if not the kind we first imagine. “Regency England is a bit more black than they show in the movies,” observes Bill, wary that in this period “slavery is still totally a thing”. Indeed, undercurrents of bondage, racism and inhumanity soon bubble to the surface.

Thin Ice is a superb episode, written by Sarah Dollard, in which Bill asks questions that cut to the core of the Doctor’s morality. Pearl Mackie is a remarkably empathic presence, while Peter Capaldi is the finest he’s ever been at the wit, fury and remoteness of the Time Lord.


The Tardis lands in Regency-era London, where the Doctor and Bill attend the last of the great frost fairs. However, sinister forces are afoot, and something is stirring under the frozen surface of the River Thames. When people begin to mysteriously vanish while on the ice, the Time Lord and his new friend are drawn into another investigation. Bill discovers the England of the past is more like the modern day than she expected, and begins to realise that not all monsters come from outer space. Starring Peter Capaldi and Pearl Mackie, with Matt Lucas as Nardole.
