Hope it airs this year
It's for the BBC (I assumed it was a series but IMDB says TV movie?).
Either way I hope it airs this year, maybe around November/December time.
I've read that this two-hour one-off drama is going to air this Christmas (possibly on BBC4).
If there aren't any skeletons in a man's closet, there's probably a Bertha in his attic.
