Escape from Pretoria is the astounding tale of how Jenkin and twoother prisoners planned their escape, made their own duplicate keys,and managed to make their way through the ten locked doors tofreedom."At around 7 pm we both unlocked our inner doors with the numberon keys we had earlier concealed in our cell.s Alex unlocked his outerdoor using the crank mechanism, after I had signalled to him with atowel that I could hear no sounds from Vermeulen's direction. Afteremerging from his cell, Alex reolocked his number two door, turningit once only, and tiptoed down to my cell to unlock my outer door... The door swung open a little and a bright shaft of light enteredthe cupboard. He's seen us, we both thought, but Alex managed toregain his grip and pulled the door closed just as Vermeulen wouldhave come into view of it."
