I'm almost too excited to write this but..for this extra-special bonus episode, I bring you none other than Adrian Dunbar: the man, the myth, the legend who plays Superintendent Ted Hastings in one of my favourite ever TV shows Line of Duty. If you're watching season six of Jed Mercurio's addictive police procedural, I suspect you will be obsessed with this interview (and yes, of course I ask him about 'H') but if you've never seen Line of Duty, I promise you'll still love it because Adrian is such a wonderful, thoughtful guest.

We had a really moving conversation about growing up in Northern Ireland at the height of the Troubles, the sudden death of his father from a brain haemorrhage, the impact this had on his family and what it meant to win a place at drama college in the midst of all the uncertainty. Plus what it's like to work with Vicky McClure and Martin Compston on Line of Duty, where he gets his catchphrases from and I ask him to call me 'fella' which was joyous.

That's it from me for season 10. I'll be back in a few weeks' time for a special Mental Health Week episode. Please do make sure you've subscribed so as not to miss out! And thank you, as ever, for listening.

If you'd like to listen to a How To Fail episode with another Line of Duty star, I interviewed the wonderful Vicky McClure aka Kate Fleming way back in Season 4. You can find it here.
