Terry Holdbrooks arrived at Guantánamo detention camp in the summer of 2003 as a godless 19-year-old with a love of drinking, hard rock music and tattoos. By the time he left Cuba the following year, he had alienated his army colleagues, won the respect of the detainees and, most astonishingly, converted to Islam in a midnight ceremony in the presence of one of the detainees, who had become his mentor.
When I meet Holdbrooks, now 26 and named Mustafa Abdullah, he is wearing a black Muslim cap, a thick beard and long-sleeved traditional robes that almost obscure the tattoo on his right arm that reads "by demons be driven".
Holdbrooks grew up in Arizona, the only son of junkie parents who split up when he was seven years old. He was raised by his ex-hippie grandparents. Tired of being poor, determined not to follow in his parents' footsteps and keen to see the world, Holdbrooks signed up for the military. He was stationed with the 253rd Military Police Company, mostly doing administrative support work, when he was told he was to be deployed to Guantánamo.
