The episode title for Neil Gaiman’s upcoming series 6 story has been revealed by SFX. The fourth episode of the new series is called “The Doctor’s Wife”, an intriguing title, especially after Gaiman previously revealed the episode will include "an old acquaintance with a new face". The episode guest stars Suranne Jones who previously played Mona Lisa in SJA.

Yesterday Steven Moffat tweeted Neil Gaiman saying: “Ohh, just watched your one again! It's really good, isn't it? And look who it is! LOOK WHO IT IS!!!” to which Gaiman replied: “each time I watch it I'm more impressed with Matt and Suranne, & less able to believe that you let me get away with it.”
