How a teenage misfit became the keeper of Julian Assange’s deepest secrets – only to betray him
On a recent frigid night near Reykjavik, Iceland, Sigurdur “Siggi” Thordarson slips into a bubbling geothermal pool at a suburban swim club. The cherubic, blond 21-year-old, who has been called everything in the press from “attention seeker” to “traitor” to “psychopath,” ends many of his days here, where, like most places around the city, he’s notorious. But even at a spa, he can find only the briefest moment of relaxation. Soon, the local prosecutor who is trying him for leaking financial records joins him in the tub, and Siggi quickly has to flee to another pool. “How does it feel to be the most dangerous man in Iceland?” a bather shouts across the steam.
