Greg stopped by the courthouse concession stand for a cup of coffee, even though he had already downed four cups at Jane's Diner across the street. The old man behind the counter reached for Greg's dollar with a noticeably shaky hand that looked as though it had held more cigarettes and booze than money in its lifetime.
He took his coffee and walked up the stairs to the second floor. There were about fifty people standing in the hallway outside the courtroom making small talk. He recognized a few of them, but was in no mood to start a conversation.
Only four more jurors and two alternates were needed. With a little luck, he would soon be sent on his way. The coffee tasted bitter, but he continued to sip on it anyway, just to occupy himself.
After a few minutes, a woman walked out of the courtroom and spoke to the crowd in monotone. "Good morning, ladies and gentlemen. We are ready to get started. We did not get enough jurors yesterday for the criminal trial, so we are going to use part of today's panel for that purpose. Those who are not selected for the criminal trial today must appear tomorrow at 8:00 AM for the civil trial jury selection.
"First, I will call the names of the jurors that have already been selected. When I call your name, please go into the courtroom and take your seat in the pews where you sat yesterday. Please sit in the order in which your names are called."
"Alexander Littleton… Gail Silestone… " The crowd carefully analyzed each person as he walked through the group and into the courtroom. "Mary McJohnson… William Biscayne … Judy McPhearson… John Nihmbor… Nancy Novelle…  and Troy Blockerman."
Greg nearly choked on his coffee. Troy Blockerman! That's Cynthia's husband. His blood pressure shot up like a bottle rocket, exploding into a headache.
"And now I will call the names of a portion of today's panel. Those whose names are not called will need to stay here in the courthouse since we might still need you today. I will let you know when you can go home. Again, please sit in the order in which your names are called. Elsie Olstead… Lory Lip-scomb… Greg Tenorly… "
