Evans was a smart and perceptive criminal. He successfully analyses the weaknesses of the jail officers successfully. Stephen was a new recruit to the prison set up. When he saw the injured Mcleery in the cell he was so overwhelmed that he did not even check who he really was and neither did anyone else. It did not occur to anyone to question how there could there be two persons – one in the cell and the other who had been escorted out by Stephens. It was for this very reason that friends of Evans, who, posing as the Governor on the phone, have directed Stephens that he himself should escort the person out when the exam is finished. The Governor and his officers, in effect actually lead Evans out of the prison. The question paper is left behind to mislead the Governor. This shows that Evans the criminal had enough time to study the behavior patterns of the jail officers and plan their strategy well.
