Hunting Mr X is a true crime podcast that reveals the unbelievable story behind the biggest drugs importation in Scottish history - and the man who masterminded it all, Julian Chisholm, aka Mr X.

In 1990, the former North Sea diver, along with a group of unlikely Scots, made a deal with the Cali Cartel to import £100 million of uncut cocaine into the north-west of Scotland.

In this new five-part series we take you inside Julian Chisholm’s criminal enterprise that spanned the globe. The series also hears from those involved in the huge law enforcement operation to bring him to justice and reveals how Chisholm formed links with one of Europe’s most feared gangsters while in jail before mounting a daring prison escape. 

Hunting Mr X is a podcast produced by DC Thomson newspaper titles The Press and Journal and The Courier.
