It was a Wrist Rocket slingshot; the kind with the aluminum brace that used the forearm for leverage. I had a couple of them at home and recalled the many hours of enjoyment I’d had as a child, target practicing with my slingshot in the yard, at the beach and at my father’s cabin.The slingshot could be a deadly weapon if used correctly and I knew how to use it. I still felt naked without my firearms but at least I now had a means of firing something from a distance. Sitting at my feet was a bag of marbles I’d purchased from a novelty store a few blocks away.I’d broken a few windows by slingshot in my time but breaking glass wasn’t my intention in this case. Putting a marble through the window of Camille’s room would only put her companion on the alert. What I wanted was for him to stick his ugly head out of the window so I could get a look at him. Then I’d know him if I saw him on the street.I turned off all the lights in my room, then aimed at the fire escape and let fly with a marble.Ting!A direct hit.I waited.Nothing.I fired again.Ping!The marble rattled down the fire escape.This time the blind went up.
