At last, she raised her eyes and I was only half-surprised to see that they were wet. “I prayed for her, Mr. Parker, and I can't remember the last time I ever prayed. I just prayed that she'd be okay and that whoever was on the other side-God, Buddha, Allah-would look after her. Grace was a good person.”

“I think she probably was,” I said, as she lit a final cigarette. “Did she take drugs?”

Ali shook her head vehemently. “No, never.”

“Apart from getting overinvolved with her thesis, did she seem depressed or anxious?”

“No more than any of us.”

“Was she seeing anyone?”

“She'd had a couple of flings, but nothing serious for at least a year. She would have told me.”

I watched her quietly for a time, but I knew she was telling the truth. Ali Wynn hadn't been in the car with Grace on the night that she died. More and more, Marcy Becker was looking like the most likely candidate. I sat back and examined the crowds entering and leaving the T, the tourists and locals with bags of wine and candies from Cardullos, Black Forest ham and exotic teas from Jackson's of Picadilly, bath salts and soaps from Origins. Grace should have been among them, I thought. The world was a poorer place for her passing.

“Has that helped you?” asked Ali. I could see that she wanted to leave.

“It's cleared a few things up.” I handed her my card, after writing my home telephone number on the back. “If you think of anything more, or if someone else comes around asking about Grace, maybe you'll give me a call.”

“Sure.” She picked up the card and placed it carefully in her purse. She was about to move away when she paused and placed her hand lightly on my arm.

“You think somebody killed her, don't you?” Her red lips were pressed tightly together but she couldn't control the trembling of her chin.

“Yes,” I answered. “I think somebody did.”

Her grip tightened momentarily and I felt the heat of her penetrating to my skin. “Thanks for the coffee,” she said, and then she was gone.

I spent the rest of the afternoon buying some clothes for my depleted wardrobe before heading back to Copley and the Starbucks on Newbury to read the newspaper. Reading The New York Times on a near daily basis was a habit I hadn't lost, although buying it in Boston made me feel kind of guilty, as if I had just rolled up the newspaper and used it to slap the mayor.

I didn't even notice the start of the story on the far right of the front page until I came to its continuation on page seven and saw the photograph accompanying it. A man stared out at me in black and white, a black hat on his head, and I recalled the same man nodding to me from a darkened Mercedes as I approached Jack Mercier's house, and sitting uneasily with three other people in a framed photograph in Mercier's study. His name was Rabbi Yossi Epstein, and he was dead.

According to the police report, Rabbi Yossi Epstein left the Eldridge Street shul at 7:30 P.M. on a cool Tuesday evening, the flow of traffic on the Lower East Side changing, altering in pitch, as commuters were replaced by those whose reasons for being in the city had more to do with pleasure than business. Epstein wore a black suit and a white shirt, but he was far from being the traditionalist that his exterior suggested. There were those in the shul who had long whispered against him; he tolerated homosexuals and adulterers, they said. He was too ready to take his place before the television cameras, they argued, too quick to smile and pander to the national media. He was too concerned with the things of this world and too little concerned with the promise of the next.

Epstein had made his name in the aftermath of the Crown Heights disaster, pleading for tolerance, arguing that the Jewish and black communities should put aside their differences, that poor blacks and poor Jews had more in common with each other than with the wealthier members of their own tribes. He had been injured in the riots that followed, and a picture of him in the Post, blood streaming from a wound in his head, had brought him his first taste of celebrity due to the photo's unfortunate, and unintended, similarity to representations of the suffering Christ.

Epstein had also been involved with the B'Nai Jeshurun Temple up on Eighty-ninth Street and Broadway, founded by Marshal T. Meyer, whose mentor had been the conservative firebrand Abraham Yoshua Heschel. It was easy to see why someone with Epstein's views might have been attracted to Meyer, who had fought with the Argentine generals in his efforts to find disappeared Jews. Since Meyer's death, in 1993, two Argentine rabbis had continued his work in New York, including the provision of a homeless shelter and encouraging the establishment of a gay congregation. B'Nai Jeshurun was even twinned with a congregation in Harlem, the New Canaan Baptist Church, whose preacher sometimes spoke at the synagogue. According to the Times, Epstein had fallen out with B'Nai Jeshurun and had taken to holding twice monthly services at the old Orensanz Center on the Lower East Side.

One of the reasons for the split with B'Nai Jeshurun appeared to be Epstein's growing involvement in anti-Nazi groups, including the Center for Democratic Renewal in Atlanta and Searchlight in Britain. He had established his own organization, the Jewish League for Tolerance, staffed mainly by volunteers and run from out of a small office on Clinton Street, above an empty Jewish bookstore.

According to the Times, Epstein was believed to have received considerable funding in recent weeks to enable him to commence a series of investigations into organizations suspected of anti-Semitic activities, among them the usual suspects: fanatics with “Aryan” prominent in their names and splinter groups from the Klan who had left because the Klan now frowned on burning down synagogues and chaining blacks to the back axles of pickup trucks.

Whatever his critics might have said about him, Yossi Epstein was a brave man, a man of conviction, a man who worked tirelessly to improve the lives not only of his fellow Jews but of his other fellow citizens. He was found dead in his apartment at 11 P.M. on Wednesday night, apparently after suffering some kind of seizure. The apartment, in which he lived alone, had been ransacked and his wallet and address book were missing. Foul play was suspected, according to the report, a suspicion increased by another incident earlier that night.

At 10 P.M., the office of the Jewish League for Tolerance was firebombed. A young volunteer, Sarah Miller, was working there at the time, printing off addresses for a mailing the following day. She was three days short of her nineteenth birthday when the room around her became an inferno. She was still on the critical list, with burns over 90 percent of her body. Epstein was due to be buried at Pine Lawn Cemetery in Long Island that day, following the prompt autopsy.

There was one more detail that caught my attention. In addition to his work on right-wing organizations, Epstein was reported to be preparing a legal challenge to the religious tax exemption given by the IRS to a number of church groups. Most of the names were unfamiliar to me, except for one: the Fellowship, based in Waterville, Maine. The law firm employed by Epstein to handle the case was Ober, Thayer amp; Moss of Boston, Massachusetts. It was hardly a coincidence that the firm also took care of Jack Mercier's legal affairs and that Warren Ober's son was soon to be married to Mercier's daughter.

I read through the piece again, then called Mercier's home. A maid took the call, but when I gave my name and asked to be put through to Mr. Mercier, another female voice came on the line. It was Deborah Mercier.

“Mr. Parker,” she said. “My husband is not available. Perhaps I can help you?”
