"The Haunting of Villa Diodati"
Excellent episode. Love a haunted house story, and particularly enjoyed the Doc's performance and behaviour. Bradley Walsh looked ace in the period garb.

Perhaps some of the celebs weren't as fleshed out as they could be in a longer tale, but loved the shout-out to Ada. The doc's pained reference to Bill was a nice nod too.
The butler was a joy too.
