Episode 7 - Sneak Peek

Arriving outside the shop, The Doctor looks up at a smashed window.

Kathy then steps over and she sees some policemen surrounding the area.

A Policeman then says "sorry ma'am, no civilians around here please".

Kathy then pulls her badge out and she says "Detective Kathy Yates".

The Policeman then nods "oh, my apologies".

Vastra turns to The Doctor and she says "your friend seems very useful" The Doctor smiles.
