This is the story of how boxing fell under the spell of a man named in the Irish courts as heading up one of Europe's largest criminal gangs.

This man is wanted in the United States for '[sourcing] large quantities of cocaine from South America' for sale in Europe. He has also been central to some of the most important sports deals of the past decade.

This man is Daniel Kinahan.

Boxing is Ireland's most successful international sport, but it has been hollowed out by gangland murder and intrigue.

One of the biggest sports stories of all was reported but it was reported more on the front pages than the back.

Kinahan's attempted takeover of a global sport raises all sorts of questions. Finding answers hasn't been easy.

This is Shadow Boxing.
