In a flap!

This post commemorates 25 years of the RSPB.
We were in Carlisle because I decided I ought to widen (?) my cultural experiences - a touring production of The Mousetrap was on and I have never seen it.
I would tell you 'who done it' but at the end the murderer asked us not too.
I'm off to Google 'who is the murderer' in a minute to see if the tradition of not telling really holds good.
