Disappointed, Ackers clambered into the hospital truck to inspect for himself.
Very tiny and still, Heimie Rosenburg lay on his back, arms at his sides, gazing sightlessly up at the roof of the truck. On his face remained the expression of bewildered wonder. Somebody – one of the cops – had placed his bent glasses in his clenched hand. In falling he had cut his cheek. The destroyed portion of his skull was covered by a moist plastic web.
"Who's back at the apartment?" Ackers asked presently.
"The rest of my crew," the cop answered. "And an independent researcher. Leroy Beam."
"Him," Ackers said, with aversion. "How is it he showed up?"
"Caught the rattle, too, happened to be passing with his rig. Poor Heimie had an awful big booster on that rattle… I'm surprised it wasn't picked up here at the main offices."
"They say Heimie had a high anxiety level," Ackers said. "Bugs all over his apartment. You're starting to collect evidence?"
"The teams are moving in," the cop said. "We should begin getting specifications in half an hour. The killer knocked out the vid bug set up in the closet. But -" He grinned. "He cut himself breaking the circuit. A drop of blood, right on the wiring; it looks promising."
At the apartment, Leroy Beam watched the Interior police begin their analysis. They worked smoothly and thoroughly, but Beam was dissatisfied.
His original impression remained: he was suspicious. Nobody could have gotten away so quickly. Heimie had died, and his death – the cessation of his neural pattern – had triggered off an automatic squawk. A rattle didn't particularly protect its owner, but its existence ensured (or usually ensured) detection of the murderer. Why had it failed Heimie?
Prowling moodily, Leroy Beam entered the kitchen for the second time. There, on the floor by the sink, was a small portable TV unit, the kind popular with the sporting set: a gaudy little packet of plastic and knobs and multi-tinted lenses.
"Why this?" Beam asked, as one of the cops plodded past him. "This TV unit sitting here on the kitchen floor. It's out of place."
The cop ignored him. In the living room, elaborate police detection equipment was scraping the various surfaces inch by inch. In the half hour since Heimie's death, a number of specifications had been logged. First, the drop of blood on the damaged vid wiring. Second, a hazy heel mark where the murderer had stepped. Third, a bit of burnt match in the ashtray. More were expected; the analysis had only begun.
It usually took nine specifications to delineate the single individual. Leroy Beam glanced cautiously around him. None of the cops was watching, so he bent down and picked up the TV unit; it felt ordinary. He clicked the on switch and waited. Nothing happened; no image formed. Strange.
He was holding it upside down, trying to see the inner chassis, when Edward Ackers from Interior entered the apartment. Quickly, Beam stuffed the TV unit into the pocket of his heavy overcoat.
"What are you doing here?" Ackers said.
"Seeking," Beam answered, wondering if Ackers noticed his tubby bulge. "I'm in business, too."
"Did you know Heimie?"
"By reputation," Beam answered vaguely. "Tied in with Tirol's combine, I hear; some sort of front man. Had an office on Fifth Avenue."
"Swank place, like the rest of those Fifth Avenue feather merchants." Ackers went on into the living room to watch detectors gather up evidence.
There was a vast nearsightedness to the wedge grinding ponderously across the carpet. It was scrutinizing at a microscopic level, and its field was sharply curtailed. As fast as material was obtained, it was relayed to the Interior offices, to the aggregate file banks where the civil population was represented by a series of punch cards, cross-indexed infinitely.
Lifting the telephone, Ackers called his wife. "I won't be home," he told her. "Business."
A lag and then Ellen responded. "Oh?" she said distantly. "Well, thanks for letting me know."
Over in the corner, two members of the police crew were delightedly examining a new discovery, valid enough to be a specification. "I'll call you again," he said hurriedly to Ellen, "before I leave. Goodbye."
"Goodbye," Ellen said curtly, and managed to hang up before he did. The new discovery was the undamaged aud bug, which was mounted under the floor lamp. A continuous magnetic tape – still in motion – gleamed amiably; the murder episode had been recorded sound-wise in its entirety.
"Everything," a cop said gleefully to Ackers. "It was going before Heimie got home."
"You played it back?"
"A portion. There's a couple words spoken by the murderer, should be enough."
Ackers got in touch with Interior. "Have the specifications on the Rosenburg case been fed, yet?"
"Just the first," the attendant answered. "The file discriminates the usual massive category – about six billion names."
Ten minutes later the second specification was fed to the files. Persons with type O blood, with size 11 1/2 shoes, numbered slightly over a billion. The third specification brought in the element of smoker-nonsmoker. That dropped the number to less than a billion, but not much less. Most adults smoked.
"The aud tape will drop it fast," Leroy Beam commented, standing beside Ackers, his arms folded to conceal his bulging coat. "Ought to be able to get age, at least."
The aud tape, analyzed, gave thirty to forty years as the conjectured age. And – timbre analysis – a man of perhaps two hundred pounds. A little later the bent steel window frame was examined, and the warp noted. It jibed with the specification of the aud tape. There were now six specifications, including that of sex (male). The number of persons in the in-group was falling rapidly.
"It won't be long," Ackers said genially. "And if he tacked one of those little buckets to the building side, we'll have a paint scrape."
Beam said: "I'm leaving. Good luck."
"Stick around."
"Sorry." Beam moved toward the hall door. "This is yours, not mine. I've got my own business to attend to… I'm doing research for a hot-shot nonferrous mining concern."
Ackers eyed his coat. "Are you pregnant?"
"Not that I know of," Beam said, coloring. "I've led a good clean life." Awkwardly, he patted his coat. "You mean this?"
By the window, one of the police gave a triumphant yap. The two bits of pipe tobacco had been discovered: a refinement for the third specification. "Excellent," Ackers said, turning away from Beam and momentarily forgetting him.
Beam left.
Very shortly he was driving across town toward his own labs, the small and independent research outfit that he headed, unsupported by a government grant. Resting on the seat beside him was the portable TV unit; it was still silent.
"First of all," Beam's gowned technician declared, "it has a power supply approximately seventy times that of a portable TV pack. We picked up the Gamma radiation." He displayed the usual detector. "So you're right, it's not a TV set"
Gingerly, Beam lifted the small unit from the lab bench. Five hours had passed, and still he knew nothing about it. Taking firm hold of the back he pulled with all his strength. The back refused to come off. It wasn't stuck: there were no seams. The back was not a back; it only looked like a back.
"Then what is it?" he asked.
"Could be lots of things," the technician said noncommittally; he had been roused from the privacy of his home, and it was now two-thirty in the morning. "Could be some sort of scanning equipment. A bomb. A weapon. Any kind of gadget." Laboriously, Beam felt the unit all over, searching for a flaw in the surface. "It's uniform," he murmured. "A single surface."
"You bet. The breaks are false – it's a poured substance. And," the technician added, "it's hard. I tried to chip off a representative sample but -" He gestured. "No results."
