She insisted on making tea. It came, not surprisingly, in a white pot and was served in white cups. She insisted, too, that Gabriel and Chiara refer to her only as Lena. She explained that she had worked as a teacher at a state school and for thirty-seven years had been called only Miss Herzfeld by students and colleagues alike. Upon retirement, she had discovered that she wanted her given name back. Gabriel acceded to her wishes, though from time to time, out of courtesy or deference, he sought refuge behind the formality of her family name. When it came to identifying himself and the attractive young woman at his side, he decided it was not possible to reciprocate Lena Herzfeld’s intimacy. And so he plucked an old alias from his pocket and concocted a hasty cover to go with it. Tonight he was Gideon Argov, employee of a small, privately funded organization that carried out investigations of financial and other property-related questions arising from the Holocaust. Given the sensitive nature of these investigations, and the security problems arising from them, it was not possible to go into greater detail.

“You’re from Israel, Mr. Argov?”

“I was born there. I live mainly in Europe now.”

“Where in Europe, Mr. Argov?”

“Given the nature of my work, my home is a suitcase.”

“And your assistant?”

“We spend so much time together her husband is convinced we’re lovers.”

“Are you?”

“Lovers? No such luck, Miss Herzfeld.”

“It’s Lena, Mr. Argov. Please call me Lena.”

The secrets of survivors are not easily surrendered. They are locked away behind barricaded doors and accessed at great risk to those who possess them. It meant the evening’s proceedings would be an interrogation of sorts. Gabriel knew from experience that the surest route to failure was the application of too much pressure. He began with what appeared to be an offhand remark about how much the city had changed since his last visit. Lena Herzfeld responded by telling him about Amsterdam before the war.

Her ancestors had come to the Netherlands in the middle of the seventeenth century to escape the murderous pogroms being carried out by Cossacks in eastern Poland. While it was true that Holland was generally tolerant of the new arrivals, Jews were excluded from most segments of the Dutch economy and forced to become traders and merchants. The majority of Amsterdam’s Jews were lower middle class and quite poor. The Herzfelds worked as peddlers and shopkeepers until the late nineteenth century, when Abraham Herzfeld entered the diamond trade. He passed the business on to his son, Jacob, who undertook a rapid and highly successful expansion. Jacob married a woman named Susannah Arons in 1927 and moved from a cramped apartment off the Jodenbreestraat to the grand house on Plantage Middenlaan. Four years later, Susannah gave birth to the couple’s first child, Lena. Two years after that came another daughter, Rachel.
