The British Secret Service has just learnt that the North Korean authorities are investigating the apparently unmotivated murder of a British citizen who was passing through their capital. The news is all the more shocking as the victim is none other than Sir Harold Wilberforce Clifton, one pf Her Majesty's most famous agents! Clifton had been sent to North Korea to bring back the nephew of a high-ranking official to the UK after he was indoctrinated by the Black Moon cult.
