Jon plugged the wires into his arm outlet and slowly raised the current to operating level. There was a tense moment of waiting, then 17's eye shutters suddenly closed. When they opened again the eye tubes were glowing warmly. They swept the room with one glance then focused on Jon.
The right shutter clicked shut while the other began opening and closing in rapid fashion. It was International code — being sent as fast as the solenoid could be operated. Jon concentrated on the message.
Telephone — call emergency operator — tell her "signal 14" help will—
The shutter stopped in the middle of a code group, the light of reason dying from the eyes.
For one instant Jon knew panic, until he realized that 17 had deliberately cut the power. Druce's harsh voice rasped in his ear.
''What you doing with that? None of your funny robot tricks, I know your kind, plotting all kinds of things in them tin domes." His voice trailed off into a stream of incomprehensible profanity. With sudden spite he lashed his foot out and sent 17's head crashing against the wall.
The dented green head rolled to a stop at Jon's feet, the face staring up at him in mute agony. It was only circuit 92 that prevented him from injuring a human. His motors revved up to send him hurtling forward as the control relays clicked open. He sank against the debris, paralyzed for the instant. As soon as the rush of anger was gone he would regain control of his body.
They stood as if frozen in a tableau. The robot slumped backward, the man leaning forward, his face twisted with unreasoning hatred. The head lay between them like a symbol of death.
Coleman's voice cut through the air of tenseness like a knife.
"Druce, stop playing with the grease can and get down to the main door to let Little Willy and his junk brokers in. You can have it all to yourself afterward."
The angry man turned reluctantly, but pushed out of the door at Coleman's annoyed growl. Jon sat down against the walls, his mind sorting out the few facts with instantaneous precision. There was no room in his thoughts for Druce. The man had become just one more factor in a complex problem.
Call the emergency operator — that meant this was no local matter. Responsible authorities must be involved. Only the government could be behind a thing as major as this. Signal 14—that implied a complex set of arrangements, forces that could swing into action at a moment's notice. There was no indication where this might lead, but the only thing to do was to get out of here and make that phone call. And quickly. Druce was bringing in more people, junk brokers, whatever they were. Any action that he took would have to be done before they returned.
Even as Jon followed this train of logic his fingers were busy. Palming a wrench, he was swiftly loosening the main retaining nut on his hip joint. It dropped free in his hand, only the pivot pin remained now to hold his leg on. He climbed slowly to his feet and moved towards Coleman's desk.
"Mr. Coleman, sir, it's time to go down to the ship now, should I leave now, sir?"
Jon spoke the words slowly as he walked forward, apparently going to the door, but angling at the same time towards the plump man's desk.
"You got thirty minutes yet, go sit — say—!"
The words were cut off. Fast as a human reflex is, it is the barest crawl compared to the lightning action of electronic reflex. At the instant Coleman was first aware of Jon's motion, the robot had finished his leap and lay sprawled across the desk, his leg off at the hip and clutched in his hand.
"You'll kill yourself if you touch the button!"
The words were part of the calculated plan. Jon bellowed them in the siartled man's ear as he stuffed the dismembered leg down the front ot the man's baggy slacks. It had the desired effect. Coleman's finger stabbed at the button but stopped before it made contact. He stared down with bulging eyes at the little black box of death peeping out of his waistband.
Jon hadn't waited for the reaction. He pushed backward from the desk and stopped to grab the stolen pinch bar off the floor. A mighty one-legged leap brought him to the locked closet; he stabbed the bar into the space between the door and frame and heaved.
Coleman was just starting to struggle the bomb out of his pants when the action was over. The closet open, Jon seized the heavy strap holding the second bomb on the rummy's chest and snapped it like a thread. He threw the bomb into Coleman's corner, giving the man one more thing to worry about. It had cost him a leg, but Jon had escaped the bomb threat without injuring a human. Now he had to get to a phone and make that call.
Coleman stopped tugging at the bomb and plunged his hand into the desk drawer for a gun. The returning men would block the door soon. The only other exit from the room was a frosted-glass window that opened onto the mammoth bay of the warehouse.
Jon Venex plunged through the window in a welter of flying glass. The heavy thud of a recoilless.75 came from the room behind him and a foot-long section of metal window frame leaped outward. Another slug screamed by the robot's head as he scrambled toward the rear door of the warehouse.
He was a bare thirty feet away from the back entrance when the giant door hissed shut on silent rollers. All doors would have closed at the same time: the thud of running feet indicated that they would be guarded as well. Jon hopped a section of packing cases and crouched out of sight.
He looked up over his head, where there stretched a webbing of steel supports, crossing and recrossing until they joined the flat expanse of the roof. To human eyes the shadows there deepened into obscurity, but the infrared from a network of steam pipes gave Jon all the illumination he needed.
The men would be quartering the floor of the warehouse soon. His only chance to escape recapture or death would be over their heads. Besides this, on the ground he was hampered by the loss of his leg. In the rafters he could use his arms for faster and easier travel.
Jon was just pulling himself up to one of the topmost crossbeams when a hoarse shout from below was followed by a stream of bullets. They tore through the thin roof, one slug clanged off the steel beam under his body. Waiting until three of the newcomers had started up a nearby ladder, Jon began to quietly work his way towards the back of the building.
Safe for the moment, he took stock of his position. The men were spread out through the building. It could only be a matter of time before they found him. The doors were all locked and — he had made a complete circuit of the building to be sure — there were no windows that he could force. If he could call the emergency operator the unknown friends of Venex 17 might come to his aid. This, however, was out of the question. The only phone in the building was on Coleman's desk. He had traced the leads to make sure.
His eyes went automatically to the cables above his head. Plastic gaskets were set in the wall of the building and through them came the power and phone lines. The phone line! That was all he needed to make a call.
With smooth, fast motions he reached up and scratched a section of wire bare. He laughed to himself as he slipped the little microphone out of his left ear. Now he was half deaf as well as half lame— he was literally giving himself to this cause. He would have to remember the pun to tell Alec Diger later, if there was a later. Alec had a profound weakness for puns.
Jon attached jumpers to the mike and connected them to the bare wire. A touch of the ammeter showed that no one was on the line. He waited a few moments to be sure he had a dial tone, then sent the eleven carefully spaced pulses that would connect him with the local operator. He placed the mike close to his mouth.
"Hello Operator. Hello Operator. I cannot hear you so do not answer. Call the emergency operator — signal 14—I repeat — signal 14."
