Volodya and Masha and their friends returned to Moscow some days after the invasion.

On August 25 seven men and women staged a demonstration in Red Square, raising banners that read LONG LIVE FREE AND INDEPENDENT CZECHOSLOVAKIA and to YOUR FREEDOM AND OURS. They were arrested by the KGB.

Volodya did not attend the Simchat Torah celebration in the Moscow synagogue that fall of 1968. Again, the reason he gave was concern over his security clearance.

In the course of a press conference in Paris on December 3, 1966, Premier Alexei Kosygin had remarked that “as far as the reunification of families is concerned, if some families wish to meet or if they wish to leave the Soviet Union, the road is open to them…”

There is a spring 1967 photograph of Jews on a crowded platform in the rail station in Riga, men and women in their thirties and forties, with some children, starting out on the first leg of their journey to Israel. Jews were being let out, about one thousand people every year, from the southern and western Ukraine, the Baltic states, Hungary.

One day in the fall of 1968-around the time when Richard Nixon was elected president of the United States-the Drapkins informed the Slepaks and their circle of friends that a group of Jews from Riga had been granted exit visas and would soon be leaving for Israel from Moscow. Did the Moscow circle want to meet some of the people from the Riga circle when they arrived in Moscow to pick up their visas? That was how it was done: You went to Moscow from Riga, visited the Dutch Embassy for your Israel visa and the Austrian Embassy for your transit visa, had all the required documents photographed, returned to your city to collect your family, traveled back by train to Moscow with the family, then boarded a flight to Vienna. Yes, the Moscow circle did indeed want to meet with some of the people from the Riga circle.

The meeting occurred on December 25, 1968, in the Moscow apartment of the Drapkins. Over the past months the Drapkins had introduced the group to a number of former prisoners who had been in labor camps for Zionist activities. One had served a sentence of six years. The circle had listened to accounts of the camps and to plans for the reorganization of Zionist groups. Other visitors had told of meetings that were dealing with the possible beginnings of a nationwide movement of Soviet Jews and the start of a Jewish samizdat press. David Drapkin and his wife had already decided that they and their daughter would one day emigrate from the Soviet Union. In the meantime, to sever himself entirely from assimilation, he had stopped eating Russian food and reading Russian authors.

Now, in the Drapkins’ apartment, the circle talked with six people from Riga, among them a man named Mark Blum, in his late twenties, who was not returning to Riga because he was unmarried and had no family there. Instead he was to leave for Israel shortly via Vienna. Did anyone in the group wish to give him the personal data needed by the Israelis in order for them to send the official invitations that were necessary for Soviet visa applications? Names, addresses, children, dates of birth, names of parents, relatives in Israel. He would give the information to the Israelis, who would then search for the relatives. In cases of the total absence of relatives, the Israeli authorities would look into the possibility of other arrangements.

Members of the group began to write down the information.

Volodya and Masha sat looking at each other. It was late evening. The curtains were drawn against the winter gloom outside. Masha got to her feet and took Volodya’s hand, and they moved to a dark corner near a window and a desk and stood with their backs to the others.

Masha said quietly, “This is a special opportunity. Who knows when it might happen again? Are you ready to do it?”

Volodya, lost in fearful hesitation, did not respond.

Fighting back her apprehension about the consequences of their act upon their children, Masha said, “We must use this opportunity.”

And Volodya, after a brief silence, said, “Let’s do it,” and felt they had suddenly fallen into deep and icy waters.

The family chronicles record Masha’s uncertainty about what she might have done had Volodya refused. Made a further effort to persuade him, she maintains. There is a vague hint of divorce, but sober reality put that out of mind: Under Soviet law, she might have gained her visa to Israel and lost her young children to Volodya.

That evening Volodya and Masha transmitted to Mark Blum the necessary data on their family. That was the day, December 25, 1968, when three American astronauts flew around the moon, seventy miles from its forbidding surface, and one of them recited, for all the world to hear, the opening verses in the Book of Genesis: “In the beginning God created the heaven and the earth…”

The Slepaks had informed their older son, Sanya, then sixteen, that they intended to emigrate; but the younger son, Leonya, nine years old, knew nothing, and they would have to talk with him. Masha’s mother knew; she had given them her blessing, said she wanted to leave with them; indeed there was a remote possibility that she had cousins in Israel. Volodya’s father was unaware of his son’s and daughter-in-law’s intentions; he, too, would have to be told. But not immediately. First, they wanted to see what would come of the information they had given Mark Blum-who, in Israel, changed his name to Mordechai Lapid, became very devout, and in 1993 was killed by an Arab terrorist.

Now they waited. And lived their lives on the surface as if that evening meeting had never taken place. No one shadowed them; all appeared normal in the apartment building and in the workplace. But they had moved out of the ranks of the people and were now disloyal citizens, indeed would have been regarded as near criminals in the eyes of their Russian colleagues and coworkers had their plans become known.

During the time of their waiting, the dissident movement began to grow. Individuals of extraordinary stature, honored by the Soviet government and central to Soviet life, citizens of high privilege and national pride, such as the celebrated physicist Andrei Sakharov and the noted scholar Roy Medvedev, moved into the ranks of the human rights movement. Their works entered the illicit world of samizdat publications: Sakharov’s Progress, Coexistence, and Intellectual Freedom, a critique of the Soviet Union’s social structure; Medvedev’s Let History Judge, an exhaustive and chilling study of the Stalinist era.

The samizdat journal Khronika was established in April 1968 by the poet and editor Natalya Gorbanevskaya: a bulletin containing only basic information, without commentary; one copy typed with several carbons, the copies handed to others for retyping, the tissue-thin sheets stapled together and passed from hand to hand. No one seems to know how many that journal reached. Volodya and Masha were among those who read it. Reports of secret trials and the persecution of Lithuanian and Ukrainian Catholics, Seventh-Day Adventists, Buddhists, Jehovah’s Witnesses; stories of prisoners in psychiatric hospitals, of hunger strikes, protest letters, sudden loss of jobs, searches of apartments, arrests, visa requests, prison camps. One knew nothing of the fetid corners of the Soviet house from the official media; those stories were to be found only in publications like Khronika and, later, in others, including the clandestine Jewish publications that began to appear in the 1970s.

Early in 1969, soon after Mark Blum had left for Israel with the information the Slepaks and their friends had given him, Volodya asked his father to come to the apartment for a visit. Solomon Slepak was then seventy-six years old, silver-haired, stocky, a rugged, robust-looking man, with smooth pink features and clear brown eyes that effectively concealed the difficulties he was having with his heart.
