A few days ago Inside No 9 co-star/co-creator Reece Shearsmith posted this message on Twitter: "I've read a lot of previews that ruin the up and coming episodes ... they just can't seem to help themselves. So if you want our stories to have maximum effect.. I would say don't read anything in advance."

So there you have it from one of the people behind the series. Watch the programme, don't read the advance press. Since I saw his tweet I've been pondering about what to write in the run-up to the second episode, Mr King. what do you say to tempt people to tune in while attempting to avoid the wrath of Reece "don't use the word twist" Shearsmith.

The BBC information says the following: "Alan arrives at a small village primary school in rural Wales, and throwing himself into his new job, he still finds himself overshadowed by his much-loved predecessor, Mr King."

Does that tickle your fancy? I think it's OK to add that Shearsmith plays Alan and that Steve Pemberton plays the head in a wig that deserves its own spin-off.

This is the seventh series and I'm still learning new things about the most consistently inventive series on television in recent years. It was only listening to the Inside...Inside No 9 podcast last week (new episodes are released on BBC Sounds after each broadcast) that I discovered that Merrily, Merrily, the first episode of series seven, was the first episode totally set outside.

Which did get me wondering where else Shearsmith and Pemberton might set an episode. I had one idea that I've not come across before. In an era when everyone from susie Dent to Dan Stevens to Ant and Dec are becoming openly political I don't think Inside No 9 has ever done a political episode - apologies if they have. 

So why not do an episode about a Prime Minister who is not what you expect. Just one snag I suppose. You might have to rename it Inside No 10. 

If you miss Mr King you can catch up here.
