He repeated the message and waited. It would take time for the comm technician on duty to work it out. The communications staff would scurry about, searching for the program. Restricted to Sentinel, this contact would be its initial activation. The receiver in his ear whispered, "This is Ditch-digger in Bootstrap. Continue." "Ditch-digger. Scramble 16." Zolan hunched and tightened his shoulders to switch channels. The voice came through. "Done." "I want to speak with Colonel Hanno." "One moment, please." A short pause. "Hanno." "This is a Sentinel call. Break the seal on your copy of the Sentinel Support Plan and refer to Annex C, Section 21, line numbers 416 to 422. Note the encryption structure. I will cite the line in the structure that authenticates my request for support. Waiting." Minutes passed. Breaking the seal on the highest classification Sentinel Support Plan was a grave responsibility that Hanno would not take lightly. He would need to do it in the station's security vault with no witnesses present. The comm center would then need to be cleared of personnel other than Hanno before the exchange could proceed. Finally, the receiver whispered again. "I have the lines you refer to. Continue." "Note how the authenticator is to be stated," Zolan said. He rattled off a sequence of numbers, letters and symbols. Injecting a short, prescribed silence, he spun off another set. The authenticator was in two parts, each requiring its own style for presentation. "Authenticator confirmed," Hanno said after a pause. "State request?" "I'm in a flitter near the Gateway," Zolan said. "Request permission to come aboard and have unattended access to the spunnel transmitter for about five minutes. I will then depart." "Permission granted. Do you wish an escort from your present position to the dock?" "Yes, please send an unarmed tug to lead me through the gate, match me up, and point me at the dock. Tug operator and anyone else that observes my presence or the flitter must not repeat must not log the serial number of my flitter or any of its features. Clear all your people to beyond five meters in all direction from the passageways I'll be using, and from the spunnel comm center. I am armed with a hand weapon set for maximum effect without collateral damage to non-organics. My mission requires such precautions. Do you accept these conditions?" "I accept." "Noted. Have an unarmed guide at the air lock to precede me to the spunnel console. Instruct him to not speak to me, no questions, and to not interfere in any manner in what I do. When I've completed my work in the comm room the guide is to lead me back to the air lock. The same tug is then to get me through the Gateway, same conditions, and I'll be out of your way. When I'm gone conduct your highest-level UIPS security briefing. This mission is classified UIPS Black. Understood?" "Understood. Ready?"
