An unauthorized transmitter interfering with a Top Secret project, progress slowing to a halt, and this Bureau—" could be misled. And since it seems to be pinpointed in your home area—" "You don't have to justify yourself. Just don't hold out on me. I sometimes wonder if I've seen the complete files on this—" "You've seen all the files! Now I want answers, not questions! I'm warning you, Tremaine. Get that transmitter. I need someone to hang!" Tremaine left the hotel, walked two blocks west along Commerce Street Tremaine took off his hat. "Sure you do, Jess. It's been a while, In a back room Tremaine said, "To everybody but you this is just a "It won't take long to tell we don't know much yet." Tremaine covered the discovery of the powerful unidentified interference on the groceries and hikes back out to his place by the river." "Well, what about him?" "Nothing. But he's the town's mystery man. You know that. A little touched in the head." routine, high spirits, you know the line. All of 'em but Hull are back in the streets playin' with matches by now. I'm waiting for the day they'll make jail age." "Why Bram?" Tremaine persisted. "As far as I know, he never had any Tremaine shook his head. Tremaine got to his feet. "I'd appreciate it if you'd keep your ears and eyes open for anything that might build into a lead on this, Jess. Meantime, I'm just a tourist, seeing the sights." Tremaine.

Tremaine turned up his collar against a of the left rear tail fin whipping in the slipstream. Tremaine stopped Tremaine set off at a run, covered the two blocks to the hotel, yanked "What's the matter? Run out of signal?" "What's it to you, mister?" "Are you boys in touch with Grammond on the car set?" "Mind if I have a word with him? My name's Tremaine." him." He turned and spoke to the other cop, who muttered into the mike before handing it to Tremaine. The heavy voice of the State Police chief crackled. "What's your beef, Tremaine?" "I thought you were going to keep your men away from Elsby until I gave on me." "It's nothing we can go to court with, Grammond. And the job you were doing might have been influenced if I'd told you about the Elsby angle." Grammond cursed. "I could have put my men in the town and taken it "That's just what I don't want. If our bird sees cops cruising, he'll go underground." "You've got it all figured, I see. I'm just the dumb hick you boys use for the spade work, that it?" "Pull your lip back in. You've given me the confirmation I needed." "The smallest hyperwave transmitter Uncle Sam knows how to build weighs three tons," said Tremaine. "Bicycles are out." Grammond snorted. "Okay, Tremaine," he said. "You're the boy with all the answers. But if you get in trouble, don't call me call Washington." Back in his room, Tremaine put through a call. "It looks like Grammond's not willing to be left out in the cold, Fred. Tell him if he queers this—" "I don't know but what he might have something," the voice came back over the filtered hum. "Suppose he smokes them out—" "Don't go dumb on me, Fred. We're not dealing with West Virginia moonshiners." "Don't tell me my job, Tremaine!" the voice snapped. "And don't try out your famous temper on me. I'm still in charge of this investigation." "Sure. Just don't get stuck in some senator's hip pocket."

"There'll be nothing done against him, Miss Carroll ... unless it needs to be in the national interest." "I'm not at all sure I know what the term 'national interest' means, James. I distrust these glib phrases." "I always liked Mr. Bram," said Tremaine. "I'm not out to hurt him." "What does he do for a living?" "I have no idea." Tremaine stood up. "I'm sorry. Really sorry. I didn't mean to grill She paused. Tremaine waited. "There is one other thing," she said, "perhaps quite meaningless...." "I'd be grateful for any lead." "Bram fears the thunder." III pulled to a stop beside him. Jess leaned out, peered at Tremaine and asked: "Any luck, Jimmy?" Tremaine shook his head. "I'm getting nowhere fast. The Bram idea's a dud, I'm afraid." "Funny thing about Bram. You know, he hasn't showed up yet. I'm getting a little worried. Want to run out there with me and take a look around?" "Sure. Just so I'm back by full dark." State Police nosing around here? I thought you were playing a lone hand from what you were saying to me." "I thought so too, Jess. But it looks like Grammond's a jump ahead of me.

If there's some kind of spy ring working—" "We're up against an unknown quantity. I don't know what's behind this and neither does anybody else.

Tremaine went to the car, dropped the pistol in his coat pocket, "What do you make of it. Jimmy?" A wail sounded, a thin forlorn cry, trailing off into silence. Jess stared at Tremaine. "I'm too damned old to start believing in spooks," he said. "You suppose those damn-fool boys are hiding here, playing tricks?" "Who's looking for spies?" "Cops." "Who says so?"
