Please help me remember a brilliant sketch..

Desperately trying to remember who's in it (think it might've been Steve Coogan but I can't remember).
It's a police officer/sargeant/inspector walking around a castle reading English classics and it's an advert for an audio CD of that officer reading the classics. I can't remember who the comedian or what the sketch is for the life of me, please help!

Sounds like a Fast Show sketch?
