I have acquired a rare white rhino. I have custom-made a harness for the rhino, which has attached to it three wings or "fins", each of which includes a light rocket propeller, which are controlled via internet connection. I have swapped Schofield's customary plain black shoes with a seemingly identical pair of my own manufacture, which have small needles with a paralytic poison hidden in the soles. These needles are also remote controlled. I have similarly exchanged his reflective sunglasses.
The plan is this: next Friday afternoon at approximately 15:30 Schofield will leave his home to meet with his friend, "Mother". Meanwhile I will be four thousand feet overhead on one of my father's transport planes. As soon as Schofield steps outside I will activate the needles, paralysing him out in the open. The glasses, which include a tiny global positioning device will relay me his exact latitude and longitude. I will drop the rhino as I fly over, and direct its plummet via laptop using the position-able fins and the attached rocket propellers, leaving the Scarecrow helplessly waiting to be crushed by three solid tonnes of endangered species.
