Sven Somme was a wartime spy who fled to Britain
after spending two months evading capture and execution.
He photographed strategic German military bases in his home country
using a covert camera and sent tiny microfilms to the Allies hidden under stamps on letters.
He was caught by the Germans for spying - an offence punished by firing squad
- but managed to break out of his handcuffs and tip-toe past his sleeping guard.
He was pursued by 900 enemy soldiers with sniffer dogs and trekked for 200 miles
across snow-capped mountains, even swinging from pine trees so not to leave footprints behind.
He eventually reached neutral Sweden and safety.
