A HUNDRED MILESnorth, in San Francisco, the morning after the Marners' murder, Sunday morning, Kate headed again for the Cat Museum, feeling upbeat and determined.

If she had known about the grisly deaths of Ruthie and Helen Marner, she might not have left her secure apartment.

She hadn't read the paper or turned on the TV or radio since last Saturday, when the headlines so upset her. She didn't care to know any more about Lee Wark or about the local rash of cat killings-but it was silly to put off doing something she wanted badly to do.

She was, after all, only two hours from home, from Molena Point and safety. She could run down there anytime. Hanni wanted her to go.

Anyway, Lee Wark was probably hundreds of miles from San Francisco. Why would he hide in the city, so close to San Quentin? Why would he stay in California at all, with every police department in the state looking for him? Wark had spent plenty of time in Latin America, likely that was where he'd gone. She had, for no sensible reason, let the newspaper's sensational muckraking terrify her.

Heading up Stockton, walking fast in the fog-eating wind, resisting any smallest urge to turn back, she had gone five blocks and was beginning to feel better, was telling herself what a lovely outing this would be, how much she would enjoy the museum, was happily dodging people who were hurrying along in the other direction-to church, out to breakfast-when she noticed a man on the opposite side of the street keeping pace with her, his black topcoat whipping in the wind, the collar turned up and his black hat tipped low like the heavy in some forties' movie.

When she slowed, he slowed.

When she moved faster, he swung along just as quickly, his reflection leaping in the store windows.

He did not resemble Lee Wark; he was very straight rather than slouched, and broader of shoulder than Wark. His black topcoat looked of good quality, over the dark suit, his neatly clipped black beard and expensive hat implying a man of some substance. The very opposite of Wark. A man simply walking to church or to an early appointment, or to work in some business that was open on Sunday, maybe one of the shops near Fisherman's Wharf.

She turned up Russian Hill, disgusted with herself, angry because her heart was tripping too fast; she was letting fear eat at her. Behind her, the man continued on up Stockton, never looking her way. She felt really stupid.

Yet something about him, despite the broad shoulders and beard and nice clothes, left her sick with fear.

Had she caught a glimpse of his eyes beneath the dark brim? Lee Wark's cold gray eyes? She couldn't help it, she was overwhelmed again with that terrible panic.

Maybe she should drive down to the village with Hanni, for the week. Hanni had business there, and her family had a weekend cottage. They were so busy at work, it would be difficult for both of them to go.

"So we take a week off," Hanni had said. "While we wait for fabric orders and the workrooms. That won't kill any of our clients. Relax, Kate. I'm the boss, I say we drive down. You know the movers and shakers in the village better than I. You can help me, it's for a good cause." Hanni had whirled around the studio, kicking a book of fabric samples, twirling her long skirt, her short white hair and gold dangle earrings catching the studio lights, her brown Latin eyes laughing. "We need the time off. We deserve it!"

Kate had known Hanni only slightly in Molena Point when the family was down for weekends. She had always envied Hanni's looks, her prematurely white, bobbed hair, a woman so sleek and slim-those long lean lines-that even in faded jeans and an old sweatshirt, she could have stepped right out of Saks's window.

Strange-if Hanni hadn't been involved with the Cat Museum, very likely they wouldn't be considering the trip home just now.

It was Hanni who had awakened her interest in the Cat Museum, who had shown her photographs of the galleries. Hanni was on the board, deeply involved in the charitable institution's pending sale.

"We have to move somewhere, we're about ready to go into escrow. Twenty million for that Russian Hill property-and the taxes are skyrocketing. And so much pressure from the city-from some friend of the city, you can bet, who wants to build on that land."

Hanni shrugged. "For that kind of money, why fight it? We can build a lovely complex of galleries and gardens, and I think the old Pamillon estate, those old adobe walls and oak trees, might be perfect. That's the way the present museum was built; McCabe started by combining four private homes and their gardens. You need to go up there, Kate. You need to see it."

"Did you say McCabe?"

"Yes. You've read about him? He-"

"I… suppose I have. The name's familiar."

Only since she'd moved back to San Francisco had she tried to trace her family, from information the adoption agency was finally willing to release. Her grandfather's name had been McCabe. The agency said he'd been a newspaper columnist and an architect; they said he had not used a first name.

"If we don't find a place soon," Hanni had said, "the art collection will have to go into storage, and we'd rather not do that." Taking her hand, Hanni had given her that infectious grin. "Come with me, Kate. Jim and the kids don't care if I go, and you don't have an excuse. Come help me. You know Molena Point, you know realtors there. I want your opinion of that land."

"But I don't need to go there to tell you what I already know."

"You need a vacation."

Hanni, the mover and shaker. Kate's boss was a top-flight interior designer and a more-than-shrewd businesswoman. Kate loved working with her, she loved Hanni's enthusiasm. She loved telling people she was assistant to the well-known designer, Hanni Coon. And if Hanni wanted a week in Molena Point, what better excuse than a multimillion-dollar real estate deal?

Striding up Russian Hill, she saw no more "suspicious" men. The morning was bright, the blowing clouds sending running shadows before her across the pale, crowded houses and apartments. Climbing, she was short of breath. Out of shape. Had to stop every few blocks. If she were back in Molena Point for a week she'd walk miles-along the beach, through the village, down the rocky coast.

It would be so embarrassing to go back. She hadn't been home since the afternoon she threw her clothes in the car and took off up 101, escaping Lee Wark. And escaping her own husband. It was Jimmie who had paid Wark to kill her. That came out in the trial.

Everyone in the village knew her husband had gone to prison for counterfeiting, for transporting stolen cars, and as accessory to the murder for which Wark had been convicted-and for conspiracy to kill his own wife.

How had San Quentin let those killers escape? How could a maximum security prison be so lax? The three had overpowered a guard, taken him hostage, using prison-made weapons. A garrote made with sharpened silverware from the kitchen and strips of blanket. That must have embarrassed prison authorities. The guard was not expected to live. They had dumped him in a ditch in Sausalito, where authorities thought the men had split up. Two had apparently stolen cars, and may have taken clothes from the charity Dumpster of a local church.

Had Lee Wark come across the Golden Gate bridge into the city? He could have walked across.

Well, he wouldn't go to Molena Point, wouldn't show his face in the village while Max Harper was chief of police. Harper had come down on Wark with a vengeance, had seen that the prosecuting attorney was aware of every dirty detail, every smallest piece of evidence.

I could go back for a few days. So safe at home. And none of my real friends care that Jimmie's in prison-not Wilma, certainly not Clyde.
