Who is Preston Somerset? And why is he in North Korea?

An American facing five years of hard labour in North Korea for espionage is more into Alice in Wonderland and steampunk than nuclear missiles.

Matthew Miller had spent months in South Korea pretending to be an Englishman named “Preston Somerset”, say acquaintances who have met or worked with him. The 25-year-old native of Bakersfield, California, did not seem to have close friends, a regular job or any means of support during the months he spent in Seoul over a period of at least two years, they say. Nor did he give an inkling of any interest in nuclear-capable and unpredictable North Korea.
