Wardens assigned prisoners to groups. "Sections A and B were maximum security individual cells, section C was solitary confinement, while sections D to G were communal," he explained. "Section A prisoners had the most privileges. They could receive 30 letters a year as well as visitors."Letters were a mixed blessing, as we learned when Matanjana described the Censor Office. "Staff read both ingoing and outgoing mail. If they didn't like a sentence, they'd cut it out. Sometimes we'd receive a letter with only the address and signature left, held together by cello tape.""Certain people in the office specialized in forging handwriting. Prisoners would receive letters from their wives saying 'I'm divorcing you because I can't stay with a man who's going to be in prison for 20 years.'To learn if these letters were forgeries, inmates had to speak to someone in A section who could smuggle out a letter with a visitor. The problem was that group A prisoners weren't allowed to speak to the others. Wardens built a wall between them."We found ways to communicate," noted Matanjana. "During exercise breaks, we played tennis. By opening a ball, we could insert a note, tape it together and hit it over the wall. The wardens thought we were lousy shots." Smuggling letters also took place on Sundays when the priest came, according to our guide. "When he opened his Bible and said 'Let us pray,' everyone cast their eyes down. That's when the person next to him would put a letter in the Bible. The priest would close the book and walk out with it. Because he was considered a holy man, no one searched him."
