THIS WAS a delicate procedure requiring precision and the utmost concentration. His hand almost imperceptibly shaking and his brow furrowed into a intense expression of complete focus, a balding, professorial-looking middle-aged man in a lab coat held a pipette precariously over a bulbous flask. The flask, filled with a bubbling lime-green liquid, was poised above a flaming Bunsen burner and connected via rubber tubing to a maze of similar paraphernalia, a symphony of Erlenmeyer flasks, and test tubes. He was sat alone and by necessity in silence save for the gentle bubbling of the viscous liquid in the flask. The slightest error and the entire endeavour, representing weeks of work, would be ruined.
At this very moment there came an abrupt and urgent knock at the door. The scientist slipped from his stool and dropped the pipette straight into the flask in surprise, cursing loudly and coarsely in a broad American accent. Perhaps taking this outburst as an invitation, the door swung wide open and a distinctive figure stepped into the doorway.
