...He met Nancy that evening, who was shocked to learn he was alive. Unknown to her, however, he followed her home and witnessed the argument, for the blinds were up and the glass door open. He climbed over the low wall and entered the room. An apoplectic fit caused by the sight of him killed the Colonel instantly, and Nancy fainted. Henry's first thought then was to open the inside door and summon help, and he took the key from the now-unconscious Nancy to do so. Realizing that the situation looked very bad for him and that he himself could be charged with murder, he chose instead to flee, stopping long enough to retrieve Teddy, his mongoose that he used in his conjuring acts, which had escaped from the wooden box. However, he did drop his stick, the strange weapon that was later found, and he inadvertently carried the key off with him.
An inquest has already exonerated Nancy, having found the cause of the Colonel's death...
