The Baker of London

“Hello, Sterling. I am Detective Mason, thank you for sitting down with me today. Let’s get right into it. I understand they call you ‘the Baker’.”
Mason set down a glass of water in front of his subject at the table and met his eyes. He made sure the other was watching as he hit the ‘stop’ button on the recording device and nonchalantly sat in the chair opposite of his detainee.
The Baker snorted at him.
“What’s so funny?”
“Do all your witnesses fall for that trick, you turning off a tape recorder?”
