As usual at that time of night, the ER was a hopeless sea of confusion. The sign-in line at the front desk almost reached the entrance and ambulances were arriving at regular intervals. No one even looked at Martin as he walked down the central corridor and pushed open the gray door across from the besieged main desk. There was only one doctor in the lounge and he was engrossed in an EKG when Philips walked through to the showers.
Rapidly he showered and shaved, leaving his clothes in the corner of the room. By the sinks he found a pile of surgical scrub gear, which was the favorite apparel of the emergency room staff. He put on a shirt and pants and the surgical hat to cover his wet head. He even tied on the mask. There were many times that hospital personnel used masks outside of the OR, especially when they were suffering from a head cold.
Regarding himself in the mirror, Philips was convinced that someone would have to know him very well to recognize him. He'd not only gotten inside the hospital but he looked like he belonged. As for Harvey Hopkins, ER patients were always walking out. Philips looked at his watch. He'd used up an hour.
Charging out of the lounge, Philips crossed the ER and ran past two more policemen. He used the back stairs behind the cafeteria to reach the second floor. He wanted a radiation detector, but decided it was too dangerous to fetch the one in his office and had to search around the radiotherapy section until he found another. Then he ran back down the stairs to the main floor and hurried into the clinics building.
The elevators there were old and required operators, who had already left for the day, so Martin had to climb four flights to GYN. He had decided on the subway, sandwiched between two very unhappy businessmen, that the radiation could have been connected to GYN, but now that he had arrived, radiation detector in hand, his resolve began to falter. He had no idea what he was looking for.
Passing the main GYN waiting room, Philips turned into the smaller university clinic. It had yet to be passed over by the cleaning crew, and the area was littered with overflowing ashtrays and papers. It all looked so innocent and normal in the meager light.
Philips checked the receptionist's desk but it was locked. Trying the two doors behind the desk he found the whole area to be secured. But the locks were simple ones, which required the key to be inserted in the doorknob itself. A plastic card from the top of the receptionist's desk sufficed to open one. Martin went in, closed the door and turned on the lights.
He was standing in the hallway were he'd talked with Dr. Harper. There were two examining rooms to the left and the lab or utility room to the right. Martin selected the examining rooms first. Monitoring the detector very carefully he went over each room, slicking the detector into every cabinet and recess and even going over the examining tables themselves. Nothing. The place was clean. In the lab areas he did the same thing starting with the countertop cabinets, opening drawers, peering into boxes. At the end of the room he went over the large instrument cabinets. It was all negative.
The first response came from the wastebasket. It was a very weak reading and totally harmless, but it was nonetheless radiation. Glancing at his watch, Philips noticed that time was slipping rapidly away. In one-half-hour he was going to have to call Denise's apartment. He decided that he'd present himself only after he'd made sure Sansone wasn't holding her.
With the positive reading in the wastebasket he decided to go over the lab one more time. He found nothing until he returned to the closet. The lower shelves were filled with linen and hospital gowns, while the upper shelves had a mixture of laboratory and office supplies. Below the shelves was a hamper filled with soiled linen, which registered another weak positive reading when he pushed the probe almost to the floor.
Martin emptied out the soiled linen and went over it with the detector. Nothing. Sticking the probe into the emptied hamper Philips again got a weak response near the base. He reached down and put his hand into the enclosure. The walls and floor of the hamper were painted wood and seemed solid. With his fist he struck the bottom and felt a vibration. Taking his time he hit it all around the periphery. When he got to the far corner the board tilted slightly, then fell.back into place. Pushing in the same location Martin raised the floor of the hamper and looked beneath. Below were two shielded lead storage boxes with the familiar radiation warning logo.
The two boxes had labels indicating their origin from the Brookhaven Laboratories, which was a source of all sorts of medical isotopes. Only one of the labels was entirely legible. It contained 2-[18F] fluoro-2 deoxy-D-glucose. The other label was partially scraped off although it was also an isotope of deoxy-D-glucose.
Martin quickly opened the boxes. The first one with the legible label was moderately radioactive. It was the other box which had a significantly thicker lead shield that made the radiation detector go crazy. Whatever it was, it was very hot. Philips shut and sealed the container. Then he piled the linen back into the hamper and shut the door.
Martin had never heard of either one of the compounds, but the mere fact they were in the GYN clinic was reason enough to make them highly suspect. The hospital had extremely strict controls concerning radioactive material that was used for radiotherapy, some diagnostic work and controlled research. But none of these categories was applicable to the GYN clinic. What Philips had to know was what radioactive deoxy-glucose was used for.
Carrying the radiation detector, Philips descended the clinic stairs to the basement. Once in the tunnel system he had to slow his dash in order not to surprise the groups of medical students. But when he reached the new medical school he increased his pace, arriving at the library totally out of breath.
"Deoxy-glucose," he panted. "I need to look it up. Where?"
"I don't know," said the startled librarian.
"Shit," said Philips and turned and started toward the card catalogue.
"Try the reference desk," called the woman.
Reversing his direction, Philips went to the periodical section where the reference desk was staffed with a girl who looked about fifteen. She'd heard the commotion and was watching Martin's approach.
"Quick…" said Philips. "Deoxy-glucose. Where can I look it up?"
"What is it?" The girl eyed Martin with alarm.
"Must be some sort of sugar, made from glucose. Look, I don't know what it is. That's why I need to look it up."
"I guess you could start with the Chemical Abstract and try the Index Medicines, then…"
"The Chemical Abstract! Where's that?"
The girl pointed to a long table backed by bookshelves. Philips rushed over and pulled out the index. He was afraid to look at his watch. He found the reference as a subheading under glucose, giving him the volume and page number. When he found the article, he started to skim it but his frenzy turned the words into a meaningless jumble. He had to force himself to slow down and concentrate, and when he did he learned that deoxy-glucose was so similar to glucose, the biological fuel of the brain, that it was transported across the blood-brain barrier and picked up by the active nerve cells. But then, once inside the active nerve cells it could not be metabolized like glucose, and piled up. Down at the very bottom of the short article it said: "… radioactively tagged deoxy-glucose has shown great promise in brain research."
Martin snapped the book shut and his hands trembled. The whole affair was beginning to make sense. Someone in the hospital was conducting experiments in brain research on unsuspecting human subjects! "Mannerheim!" thought Martin, so enraged that he could taste the venom.
He was not a chemist, but he remembered enough to realize that if a compound like deoxy-glucose was made sufficiently radioactive, it could be injected into people and used to study its absorption in the brain. If it were very radioactive, which the stuff in the box in GYN was, then it would kill the brain cells that absorbed it. If someone wanted to study a pathway of nerve cells in the brain they could selectively destroy them with this method, and it was the destruction of nerve pathways in animal brains that had been the foundation of the science of neuroanatomy. To a sufficiently ruthless scientist it was just a step to adopt the same methods to humans. Philips shuddered. Only someone as egocentric as Mannerheim would be able to overlook the moral aspects.
