Where Are These Locations ?

Guardian of The Abyss

The auction rooms that appear at the beginning of the episode.

Carpathian Eagle

Outside the theatre. Was this outside Hemel Hempstead Old Town arts theatre? I thought perhaps they used part of Hampden House, although Andy Pagin who knows Hampden House very well is almost 100% certain it’s not.

Two Faces of Evil

The car crash sequence seen at the start of the episode. Surely one of the lanes near to Hampden House?
