He took his fiancee to the firm that now maintained his father. Since the transfer, Anthony had been able to afford returning to his home town to visit his father only sporadically. The distance made him anxious because the new firm didn"t inspire the confidence that the previous one had,, It looked on the edge of disrepair, floors not dirty but not clean, walls not exactly faded and yet somehow in need of painting. Rooms seemed vaguely underlit. The units in which patients were kept frozen looked cheap.

The temperature gauges were primitive compared to the elaborate technology at the previous facility. But as long as they kept his father safe...

That thought left Anthony when he took another look at the gauge and realized that the temperature inside his father"s chamber had risen one degree from when he"d last checked it.

"What"s wrong?" his fiancee asked.

Words caught in his throat. All he could do was point.

The temperature had gone up yet another degree.

He raced along corridor after corridor, desperate to find a maintenance worker. He burst into the company"s office and found only a secretary.

"My father..."

Fl.u.s.tered, the secretary took a moment to move when he finished explaining. She phoned the control room. No one answered.

"It"s almost noon. The technicians must have gone to lunch."

"For G.o.d"s sake, where"s the control room?"

At the end of the corridor where his father was. As Anthony raced past the niche, he saw that the temperature gauge had gone up fifteen degrees. He charged into the control room, saw flashing red lights on a panel, and rushed to them, trying to figure out what was wrong. Among numerous gauges, eight temperature needles were rising, and Anthony was certain that one of them was for his father.

He flicked a switch beneath each of them, hoping to reset the controls.

The lights kept flashing. He flicked a switch at the end of their row.

Nothing changed.

He pulled a lever. Every light on the panel went out. "Jesus."

Pushing the lever back to where it had been, he held his breath, exhaling only when all the lights came back on. The eight that had been flashing were now constant.

Sweating, he eased onto a chair. Gradually, he became aware of people behind him and turned to where his fiancee and the secretary watched in dismay from the open door. Then he stared at the panel, watching the temperature needles gradually descend to where they had been. Terrified that the lights would start flashing again, he was still concentrating on the gauges an hour later when a bored technician returned from lunch.

It turned out that a faulty valve had restricted the flow of freezant around eight of the niches. When Anthony had turned the power off and on, the valve had reset itself, although it could fail again at any time and would have to be replaced, the technician explained.

"Then do it!"

He would never again be comfortable away from his father. It made him nervous to return to medical school. He contacted the cryofirm every day, making sure that there weren"t any problems. He married, became a parent (of a lovely daughter), graduated, and was lucky enough to be able to do his internship in the city where he"d been raised and where he could keep a close watch on his father"s safety. If only his father had been awake to see him graduate, he thought. If only his father had been cured and could have seen his granddaughter being brought home from the hospital...

One night, while Anthony was on duty in the emergency ward, a comatose patient turned out to be the broker who"d married his mother. The broker had shot himself in the head. Anthony tried everything possible to save him. His throat felt tight when he p.r.o.nounced the time of death.

He joined a medical practice in his hometown after he finished his internship. He started earning enough to make good on his promise and take care of his wife after she"d spent so many years taking care of him. She had said that she wanted three children, and she got them sooner than she expected, for the next time she gave birth, it was to twins, a boy and a girl. Nonetheless, Anthony"s work prevented him from spending as much time with his family as he wanted, for his specialty was blood diseases, and when he wasn"t seeing patients, he was doing research, trying to find a way to cure his father.

He needed to know the experiments that the lab had conducted and the types of rays that his father might have been exposed to. But the lab was obsessed with security and refused to tell him. He fought to get a court order to force the lab to cooperate. Judge after judge refused. Meanwhile he was terribly conscious of all the family celebrations that his father continued to miss: the day Anthony"s first daughter started grade school, the afternoon the twins began swimming lessons, the evening Anthony"s second daughter played "Chopsticks" at her first piano recital. Anthony was thirty-five before he knew it. Then forty. All of a sudden, his children were in high school. His wife went to law school. He kept doing research.

When he was fifty-five and his eldest daughter turned thirty (she was married, with a daughter of her own), the laboratory made a mistake and released the information Anthony needed among a batch of old data that the lab felt was harmless. It wasn"t Anthony who discovered the information, however, but instead a colleague two thousand miles away who had other reasons to look through the old data and recognized the significance of the type of rays that Anthony"s father had been exposed to. Helped by his colleague"s calculations, Anthony devised a treatment, tested it on computer models, subjected rats to the same type of rays, found that they developed the same rapid symptoms as his father had, gave the animals the treatment, and felt his pulse quicken when the symptoms disappeared as rapidly as they had come on.

With his wife next to him, Anthony stood outside his father"s cryochamber as arrangements were made to thaw him. He feared that the technicians would make an error during the procedure (the word echoed from his youth), that his father wouldn"t wake up. His muscles tightened as something hissed and the door swung open. The hatch slid out.

Anthony"s father looked the same as when he"d last seen him: naked, gaunt, and gray, suspended over a force field.

"You thawed him that quickly?" Anthony asked.

"It doesn"t work if it isn"t instantaneous."

His father"s chest moved up and down.

"My G.o.d, he"s alive," Anthony said. "He"s actually..."

But there wasn"t time to marvel. The disease would be active again, racing to complete its destruction.

Anthony hurriedly injected his father with the treatment. "We have to get him to a hospital."

He stayed in his father"s room, constantly monitoring his father"s condition, injecting new doses of the treatment precisely on schedule. To his amazement, his father improved almost at once. The healthier color of his skin made obvious what the blood tests confirmed-the disease was retreating.

Not that his father knew. One effect of being thawed was that the patient took several days to wake up. Anthony watched for a twitch of a finger, a flicker of an eyelid, to indicate that his father was regaining consciousness. After three days, he became worried enough to order another brain scan, but as his father was being put in the machine, a murmur made everyone stop.

"... Where am I?" Anthony"s father asked.

"In a hospital. You"re going to be fine."

His father strained to focus on him. "... Who?..."

"Your son."

"No.... My son"s...a child." Looking frightened, Anthony"s father lost consciousness.

The reaction wasn"t unexpected. But Anthony had his own quite different reaction to deal with. While his father hadn"t seen him age and hence didn"t know who Anthony was, Anthony"s father hadn"t aged and hence looked exactly as Anthony remembered. The only problem was that Anthony"s memory came from when he was nine, and now at the age of fifty-five, he looked at his thirty-two-year-old father, who wasn"t much older than Anthony"s son.

"Marian"s dead?" Anthony reluctantly nodded. "Yes. A car accident."

"When?"

Anthony had trouble saying it. "Twenty-two years ago."

"No."

"I"m afraid it"s true."

"I"ve been frozen forty-six years"! No one told me what was going to happen."

"We couldn"t. You were unconscious. Near death."

His father wept. "Sweet Jesus."

"Our house?"

"Was sold a long time ago."

"My friends?"

Anthony looked away.

With a shudder, his father pressed his hands to his face. "It"s worse than being dead."

"No," Anthony said. "You heard the psychiatrist. Depression"s a normal part of coming back. You"re going to have to learn to live again."

"Just like learning to walk again," his father said bitterly.

"Your muscles never had a chance to atrophy. As far as your body"s concerned, no time pa.s.sed since you were frozen."

"But as far as my mind goes? Learn to live again? That"s something n.o.body should have to do."

"Are you saying that Mom and I should have let you die? Our lives would have gone on just the same.

Mom would have been killed whether you were frozen or you died. Nothing would have changed, except that you wouldn"t be here now."

"With your mother gone..."

Anthony waited. "With my son gone..."

"I"m your son."

"My son had his ninth birthday two weeks ago. I gave him a new computer game that I looked forward to playing with him. I"ll never get to see him grow up."

"To see me grow up. But I"m here now. We can make up for lost time."

"Lost time." The words seemed like dust in his father"s mouth.

"Dad"-it was the last time Anthony used that term-"this is your grandson, Paul. These are your granddaughters Sally and Jane. And this is Jane"s son, Peter. Your great-grandson."

Seeing his father"s reaction to being introduced to grandchildren who were almost as old as he was, Anthony felt heartsick.

"Forty-six years? But everything changed in a second," his father said. "It makes my head spin so much..."

"I"ll teach you," Anthony said. "I"ll start with basics and explain what happened since you were frozen.

I"ll move you forward. Look, here are virtual videos of-"

"What are virtual videos?"

"Of news shows from back then. We"ll watch them in sequence. We"ll talk about them. Eventually, we"ll get you up to the present."

Anthony"s father pointed toward the startlingly lifelike images from forty-six years earlier. "That"s the present."

"Is there anything you"d like to do?"

"Go to Marian."

So Anthony drove him to the mausoleum, where his father stood for a long time in front of the niche that contained her urn.

"One instant she"s alive. The next..." Tears filled his father"s eyes. "Take me home."

But when Anthony headed north of the city, his father put a trembling hand on his shoulder. "No.

You"re taking the wrong direction."

"But we live at-"

"Home. I want to go home"

So Anthony drove him back to the old neighborhood, where his father stared at the run-down house that he had once been proud to keep in perfect condition. Weeds filled the yard. Windows were broken.

Porch steps were missing.

"There used to be a lawn here," Anthony"s father said. "I worked so hard to keep it immaculate."

"I remember," Anthony said.

"I taught my son how to do somersaults on it."

"You taught me."

"In an instant." His father sounded anguished. "All gone in an instant."

Anthony peered up from his breakfast of black coffee, seeing his father at the entrance to the kitchen.

It had been two days since they"d spoken.

"I wanted to tell you," his father said, "that I realize you made an enormous effort for me. I can only imagine the pain and sacrifice. I"m sorry if I"m... No matter how confused I feel, I want to thank you."

Anthony managed to smile, comparing the wrinkle-free face across from him to the weary one that he"d seen in the mirror that morning. "I"m sorry, too. That you"re having such a hard adjustment. All Mom and I thought of was, you were so sick. We were ready to do anything that would help you."

"Your mother." Anthony"s father needed a moment before he could continue. "Grief doesn"t last just a couple of days."
