Crime by Heath Kelly Premium Content Subscriber only As the first blow from a Grafton Jail prison guard rained down there was one thought on new arrival Bernie Matthews' mind - "Don't make a sound, don't yell out." It was the early 1970s and Matthews had been transferred to the hellhole of Grafton after trying to escape from Parramatta Jail, breaking one of the five cardinal rules of prison life. The others being don't kill a prison guard, don't assault a prison guard, don't actually escape, and don't participate in a riot. "If you broke any one of those cardinal rules, and I'd broken about four of them already, that earned you a trip to the intractable section of Grafton Jail and Grafton had a reputation and that reputation was brutality, that when you went there they were going to knock it all out of you."
