“ THE MAGICIAN OF CANNON STREET. MY reason for going down to Cannon Street at all that morning was not connected in any way with crimes and mysteries—I had no idea of either in my mind when I stepped out of the Underground at the Mansion House Station. I was on a much pleasanter errand than the solving of problems arising from crimes ”
