There were eight feet between the deposit box and the master keyhole by the door. Not only was it impossible for one person to open the door unassisted, but whoever stood by the master keyhole would be visible to the security guards. Artemis pulled his scooter from the backpack. He yanked one pin from its socket, detaching the steering column from the footrest. This was no ordinary scooter. An engineer friend of Butler 's had constructed it from very specific blueprints. The footrest was completely regular, but the steering column turned into a telescope at the touch of a spring-release button. Artemis unscrewed on e handgrip, reattaching it at the other end of the column. There was a slit in the end of each grip, into which Artemis screwed a master key. Now all he had to do was insert both keys into their corresponding keyholes and turn them simultaneously.
Artemis slotted one key into Crane and Sparrow's box.
'Ready?“ he asked Butler.
'Yes,“ replied his bodyguard. ”Don't go one step farther than you have to.“
'Three, two, one. Go.“
