And just two weeks after Kavanaugh's sentencing, the United States raised the stakes.

You've been listening to an extract from our nine-part series, The Science of Fear, about the rise and fall of Daniel Kinahan's right-hand man, Thomas Bomber Kavanagh.

To listen to all nine parts, log on to crimeworld.com and hit subscribe.

So you know it's not a crime to be fascinated by all things criminal.

And if you do like delving into the underworld, why not join us for a special live show on March 27th at the Cork Opera House.

We'll be talking about the making of a cartel and all the wild and crazy stories that happened along the way.

So why not join us for this special live show?

You see, we just drop you in when you're sort of, you're expecting because you're here a while and then you're least expecting it because you're just having a conversation all of a sudden we're recording.

Yes, lovely.

Spencer Matthew, welcome very much to the show.

You're not the usual character we have sitting here, but you're here in Dublin to promote Benicol and what you call habit stacking, which is when you do lots of good things that result in better health.

Why am I not your normal guest?

I don't know.

You tell me.

Is there something that you have that is particularly attuned to the goings on of organized crime?

Or have you built up a reputation for yourself as a major gangland figure?

Well, not yet.
