"Tell the district attorney I'm visiting our national shrines in order to renew my commitment to our precious civil liberties," said Karp. "He'll understand."

At 5:15, Karp was immersed in a case, writing notes for one of his people, when the intercom buzzed, and Connie Trask said, "I'm going. Want anything?"

"No, go ahead."

"Don't forget the kid."

"Oh, shit!" cried Karp, looking at his watch to confirm that yet again he had left his daughter waiting at the day care on Lispenard Street. He shoved some reading into an old red pasteboard folder and cleared the building in three minutes.

Six minutes after that, he was at the day care, a cheerily decorated Tribeca storefront, at Lispenard off Broadway. Karp went in and found his daughter playing with a small ocher girl (they were the last two kids in the place) and Lillian Dillard, the proprietor. Dillard, known to all as Lillie-Dillie, was an unflappable ex-hippie who wore her graying hair in a long plait that hung to her tailbone, and favored fashion statements that included tentlike smocks made of Indian bedspreads and lots of clanking silver. She had somehow, in the midst of her serious participation in the sixties, obtained a degree from NYU in early-childhood education, and she ran her operation with love and a slightly wacky efficiency. Her most valuable trait in Karp's eyes was that she allowed forgetful dads to pick up their kids a half hour after the agreed time without coming in for a load of horseshit.

Lucy Karp caught sight of her father and, as usual, shrieked, "Daddy, Daddy, Daddy," flung herself into his arms, and otherwise behaved as if he had just returned safely from four years on the Western Front. Karp did not mind this one bit.

He hugged her and inhaled that ineffable smell that rises from the skin of well-tended young children: eau de kid, the world's most expensive fragrance. He put the three-year-old down, found the lunch box and the drawing to show Mommy, said good-bye to Lillie-Dillie, and they headed off, hand in hand, north on Broadway. As usual, they stopped as Dave's for a couple of chocolate egg creams, which they sipped at the marble outside counter.
