That gave him another idea. Reaching for his voicewrite, he dictated a concise confidential memorandum instructing Assistant Administrator Eglin to outfit an investigatory mission immediately; purpose, to go to Venus and make contact with Lang. The terraforming group was nearly two weeks overdue in its scheduled report. He could not ignore them any longer. The everlasting annunciator chimed, and Walton switched on the screen. It was Sellors, and from the look of abject terror on the man's face, Walton knew that something sticky had just transpired. "What is it, Sellors? Any luck in tracing Lamarre?" "None, sir," the security chief said. "But there's been another development, Mr. Walton. A most serious one. _Most_ serious." Walton was ready to expect anything--a bulletin announcing the end of the universe, perhaps. "Well, tell me about it," he snapped impatiently. Sellors seemed about ready to collapse with shame. He said hesitantly, "One of the communications technicians was making a routine check of the building's circuits, Mr. Walton. He found one trunk-line that didn't seem to belong where it was, so he checked up and found out that it had been newly installed." "Well, what of it?" "It was a spy pickup with its outlet in your office, sir," Sellors said, letting the words tumble out in one blur. "All the time you were talking this morning, someone was spying on you." Walton grabbed the arms of his chair. "Are you telling me that your department was blind enough to let someone pipe a spy pickup right into this office?" he demanded. "Where did this outlet go? And is it cut off?" "They cut it off as soon as they found it, sir. It went to a men's lavatory on the twenty-sixth floor." "And how long was it in operation?" "At least since last night, sir. Communications assures me that it couldn't possibly have been there before yesterday afternoon, since they ran a general check then and didn't see it." Walton groaned. It was small comfort to know that he had had privacy up till last evening; if the wrong people had listened in on his conversation with McLeod, there would be serious trouble. "All right, Sellors. This thing can't be your fault, but keep your eyes peeled in the future. And tell communications that my office is to be checked for such things twice a day from now on, at 0900 and at 1300." "Yes, sir." Sellors looked tremendously relieved. "And start interrogating the communications technicians. Find out who's responsible for that spy circuit, and hold him on security charges. And locate Lamarre!" "I'll do my best, Mr. Walton."
