In Northern Ireland, from the late 70s to the early 90s, the IRA killed over 40 alleged informers.

But the man who often found, tortured and sometimes killed these people on behalf of the IRA

was himself an informer, a secret British army agent with the codename Stakeknife.

Who gets to play God? And why me? Why my family? When lies are still being told to this day,

Steakknife. Listen first on BBC Sounds. This is the BBC.

Hello, today a novel once described as the most outrageously funny book about sex yet written,

but will we all find it funny?

With me today are the actor-writer and comedian Katie Brand, whose most recent solo shows have

included I was a teenage Christian and I could have been an astronaut.

She's appeared in films and in TV dramas such as the BBC's Map and Lucia,

and she has published so far one novel.

Brenda Monk is funny.

With Katie, his fellow stand-up and presenter Nish Kumar.

His series for BBC radio include most recently Spotlight Tonight and on TV, besides appearing on panel shows such as QI and Have I Got News View, is the host of BBC 2's satirical news programme, The Mash Report.

Katie Bran, could I ask you first, what's your choice of a good read?

My choice is Port Noise Compl's complaint by Philip Roth.

Thank you so much for giving us this book to discuss on radio.

You're welcome.

It's going to be quite complicated.

Tell us what it's about and why.

Well, it's about a man.
