SIR - One day during a routine shopping trip to the city I had an unexpected treat to witness some filming outside the Guildhall.

Fascinated to discover, thanks to the clapper board, the feature was a Father Brown story.

Between takes I was near enough to have a few words with the Director.

To my question, was this for television, he replied, are you familiar with the Father Brown stories?

It gave me great pleasure to answer yes, thanks to G K Chesterton!

He went on to tell me, there would be ten episodes on the BBC sometime in January.

Then, visiting the Guildhall shop, I was informed by a friendly assistant that all week they had been filming.

Most definitely something to which I shall look forward especially as a resident of our fair city.

MRS JEAN Harris Worcester
