Clara is alone in Victorian London with a man she doesn't know, a dinosaur in the Thames, and a spate of deadly spontaneous combustions. The Doctor has changed. It's time you knew him.

Christmas Eve 1892, and the falling snow is the stuff of fairytales. When the fairytale becomes a nightmare and a chilling menace threatens Earth, an unorthodox young governess, Clara, calls on the Doctor for help. But the Doctor is in mourning, reclusive and determined not to engage in the problems of the universe. As old friends return, will the Doctor really abandon humankind or will he fight to save the world – and Christmas – from the icy clutches of this mysterious menace?

Clara is summoned to an impossible conference call, alerting her that the deadly Whisper Men are closing in on Vastra, Jenny and Strax. Someone is kidnapping the Doctor's friends, leading him toward the one place in all of time and space that he should never go. It's a deadly trap that threatens to unravel his past, present and future...
