Lost twins? Shock horror!

Approaching Marple Bridge from distant Glossop, and still a mile or more before reaching what I regard as my beat, I was surprised to see this sign in a remote lay-by:

We have a twin! Nay twins! Callooh Callay.

But where are they? Has anybody seen?

Hold the front page! I must find out more.

Fear not. I'll report back with a special late edition before Friday's out.

Your intrepid local scout,

Tom.
