An ambulance, which had been summoned, arrived, and they saw the guard lifted into the vehicle. Two other guards climbed in beside him. “Remember, no one is to talk with him until I arrive,” Merritt Hughes ordered. As they turned to re-enter the building, the federal agent spoke to Bob. “Tully Ross got here just before the guard was found. Come along upstairs while I question him.” They were waiting for the elevator when a short, thick-set man hastened in. He was scowling and obviously had been routed out of bed. Merritt Hughes turned to greet the newcomer and as he recognized him there was no cordiality in the greeting. “Hello, Adams,” he said. “I didn’t expect to see you here tonight.” “I’ll bet you didn’t,” snapped the other, “but don’t think for a minute you can bull-doze my nephew and get away with it.” “What do you mean?” “You know darned well what I mean. Didn’t you just phone Tully Ross and order him down here; didn’t you practically threaten him?” “I wouldn’t call it exactly a threat, but I did tell him to get down here at once if he knew what was good for him. No clerk is going to be impudent with me.” Merritt Hughes spoke firmly and calmly, but there was something in the flash of his eyes that told Condon Adams that he had gone far enough. “If you want to come along while I talk with Tully, you’re quite welcome,” he added. Condon Adams grunted and shouldered his way ahead of them and into the elevator. They were silent as they rode up to the top floor and strode down the corridor to the office where Tully Ross was waiting for them. Tully’s dark, rather handsome face, was marked by frowns as he saw Bob enter behind Merritt Hughes. “Now what’s been going on here?” demanded Condon Adams as he surveyed the room with cool, calculating eyes. Suddenly he saw the radio file and he swung to face Merritt Hughes. “This case getting hot?” He shot the question out in short, chopped-off words. Bob’s uncle nodded. “Looks like it.” “Fine one you are not to let me know,” said Adams bitterly. “I don’t recall that you’ve ever tipped me off to any breaks in any case we’ve worked on before,” said Merritt Hughes coolly. “When you get in that habit I’ll try to learn your telephone number.” Condon Adams snorted. “About what I expected. Well, let’s get along here. What happened?” “You’ll learn all that in good time,” said Bob’s uncle. “Right now I’m in charge and I want to know why Tully came up to the office tonight and why he tried to look through the radio file. Speak up, Tully.” “There isn’t much to tell,” began Tully. “I was going by and when I saw the lights on in the office I came up. Just curiosity, I guess.” “Sure it wasn’t anything more?” “Sure.” “Then why did you try to look into the radio file?” Tully shot a bitter glance at Bob for he realized that Bob was the only source of information on his activities while he was in the room.
