“Here, I will throw you a file, and you cut through your cell door, and I will do the same, and I have friends who are going to help me. Now, don’t wait too long.”

If any one had been listening they would have heard the distinct buzzing of two tiny files making their way through the steel bars in the cells of two convicts.

When the task was over Tom Cooper stood a free man in the corridor.
