operation completed, the two scientists carefully manoeuvred one of the spheres to the end of the laboratory and steered it gently out through doors which opened automatically as the trolley approached. Hardly had the doors closed than Bond had entered the laboratory and was moving swiftly to the distillation system. He pulled open the door of the refrigerator and selected one of the phials from the batch that had recently been introduced. Others were covered by a thick rime of frosting. He listened attentively for sounds of the scientists returning and then crossed to the remaining sphere. He must check that the contents of the phial in his hand were identical to those of the sphere. The lid of the conning tower was spring-loaded and it was necessary to lay the phial he had taken from the refrigerator on one of the wings so that he could grapple with it. He had just succeeded in opening the lid when he heard the sound of returning voices. Telling himself to keep calm, Bond carefully inserted his thumb and forefinger in the opening and closed them about the lip of a phial. He started to withdraw it and felt the phial tremble as it worked free from his desperately pinching fingers. Cocking his little finger, he was able to support the lid and liberate his hand to grasp the phial just before it dropped. The automatic doors slid open as he ducked down and tucked the phial into the breast pocket of his pullover. Skirting the racks of instruments and the work benches, he returned to the outer office and gently pushed the door closed behind him before rising to his feet. Experience told him that this was the moment to get out and not push his luck, yet he could not resist looking back into the laboratory. The two scientists had returned to the second globe and were preparing to manoeuvre it towards the automatic doors. Damn! Bond nearly spoke the word as he realized that he had left the phial taken from the refrigerator on the globe’s centre section. The scientists could scarcely fail to see it. He was turning away when the trolley began to move and he heard a cry of alarm that penetrated even the thick glass of the observation panel. One of the scientists lunged forward desperately and the trolley lurched. Bond realized what must have happened. The first movement of the trolley had caused the phial to roll off the globe. What seemed like a puff of green smoke hung in the air and a bright red light in the ceiling of the laboratory started flashing at the same time as a piercing alarm bell began to ring. With a hissing noise, a green airtight seal appeared around the framework of the door by which Bond had entered the laboratory. As he watched, horrified, the scientists began to stumble towards the automatic doors. One collapsed against a rack of instruments and dragged them with him to the ground. The other reached the doors to find that they did not open. He beat at them with his fists and tried pathetically to prize them apart with his fingers. Within seconds he was clutching at his throat and then sliding down the doors to disappear from view. The air inside the laboratory was now tinged with green and a sinister coating of green appeared on the inner surface of the viewing panel like slime on the side of an aquarium. Only the rats seemed unaffected and still nosed inquisitively against the bars of their cages. Bond took a wary breath and felt the outline of the phial against his chest. It would have been less dangerous had it contained nitro-glycerine. Eager to escape from the hellish scene before him, he pressed the switch that opened the door to the corridor and quickly retraced his steps to the flight of steps and the courtyard. Now the alarm bell was only a distant buzz and the wrought iron gate that led to safety was only a few paces away. Bond quickly crossed the courtyard and pulled open the gate. The gondola was not that. He looked towards the intersection that led to the main waterway and saw that it was drifting
