Nicola Tallant, top Irish crime journalist and author of Groomed: Coercion, Control and a Cold-blooded Murder, joins me to discuss the horrific murder of Katie Simpson, a 21-year-old showjumper in Northern Ireland who fell into the clutches of Jonathan Cresswell, a horse trainer (pictured) who was also her brother-in-law. This is the government review she mentions in the episode: https://www.justice-ni.gov.uk/publications/katie-simpson-review

Polly Rippon, a former court reporter with the Sheffield Star who now teaches journalism at Sheffield University, joins me to discuss the art of court reporting and why it is so important. We talk about why trials are covered differently than they were in the past, why it can be dangerous for untrained people to cover cases, and some of the social issues which have only been unearthed by court reporting. This, by the way, is the Sheffield case I mention during the first part of our talk. http://news.bbc.co.uk/1/hi/uk/1190207.stm

In this episode I am joined by Loukas Ntanos, a criminologist from Birmingham City University and an expert on murderabilia - which is the collection of items related to homicide cases. Yes, believe it or not, there are people out there who collect and trade in ghastly souvenirs of serial killers such as Frederick Deeming (pictured) and infamous crimes. It's a fascinating subject which Loukas has been researching.
