Well-loved national hero, or predatory paedophile? So Great a Crime tells the true story of 'Fighting Mac' Sir Hector MacDonald who rose from humble beginnings as a crofter's son through the ranks of the British Army to become a knight of the realm, hero of the Battle of Omdurman and Queen Victoria's favourite general.

Allegations of liaisons with young boys surface and MacDonald is forced to return home. Rather than face a court martial, he shoots himself in a Paris hotel. But was he guilty?
