Gym

He always went to the gym early. He said it was because it was quiet at that time of day and all the machines were free.
There was truth in this, but it didn't tell the whole story.
He'd assume the position to bench a hundred kilos or so and then take out a book and begin reading.
This was his routine every day. Nobody ever saw him.
He'd throw a little water over his shirt before he left to make it look like he'd been sweating and then go to the cool cafe where they did the best breakfast.
Today was different though. There was another man in there. He looked shifty. They stared at each other for almost ten minutes, a kind of stand-off developing. Eventually they both chose a bench and took out their books.
