Even though the prison staff has rehearsed the killing of a man several times so they'll be good at it when the time comes, it's different now that it is actually happening for real. I feel that by now he has been moved and strapped down to the deathbed. Fourteen minutes until the plunger is pushed by the executioner. The twelve witnesses are sure to he watching his every movement, listening for whatever sounds a condemned man would make. Seven minutes now.
Time goes by so fast when it is most precious.

He must know it's over for him, because there's a clock for him to see.
