Suddenly, Steel froze on the spot and looked over at the boards. ‘Could it be that simple?’ He spoke softly as if nobody else was present. Then, rushing over to the first board, he examined the pictures and did the same for the others. McCall and the others looked at Steel as if he had just gone mad. Steel’s hand moved from picture to picture as if searching for something. Then he stopped and rushed towards the elevator. ‘What’s the matter, coffee get to you?’ she called after him. ‘No, the marks did,’ he said as the elevator door opened. McCall stared across at Tony and Tooms, who were just as confused as she was. Tony made a crazy person gesture with his index finger, and seconds later, they all jumped up and followed him, in case they’d missed something that he had picked up on.
