"Peaky Blinders" BBC2 Episode 6 Series final... Series 2?

I hope a second series is not made. But it will be. Campbell (Sam Neill) probably topped himself rather than Grace. Tom may have some adventures in New York (steering clear of Nucky Thompson's territory, of course).
The search must be now on for a replacement arch-nemesis for Tom and the Shelbys. The character of Aunt Pol (Helen McCrory) is too good to waste. Wasn't she brilliant in Episode 6 - the pub scene with Grace? This stylish series will play well overseas. Its ratings in the UK weren't shabby either.
I just wish shows would stop when they're on a high. Remember "Dexter"?
On the other hand BBC cancelled the wonderful "The Hour" (also on a cliffhanger). The show could have have a third series - look at all the juicy 60's news they could have used (e.g. the Profumo affair). Just when retro shows are so popular ("Mad Men","Call the Midwife", "Masters of Sex", "Breathless"). Perhaps there's a glut of these late 50's/early 60's TV shows.
