Wilma had reminded him that cats were strange. "That," she said, grinning at him, "is the very nature of cats."

"Hey, this is beyond strange. This is impossible."

Wilma shrugged, pushed back a strand of hair that lay tangled over her shoulder. "Cats' strange habits and strange perceptions, that's part of their charm. Read any cat magazine, look at the letters they receive from readers. Cats are admired for their peculiar behavior, their sometimes almost-human behavior."

She had recounted a dozen stories about the strange deportment of individual cats. She told him about a cat who would lie beside the telephone recorder and punch the button to hear the little message his mistress had left. She told him about a cat who liked to unravel balls of yarn, and while doing so would weave the yarn around chair legs, back and forth into intricate and sophisticated patterns.

"That," Clyde said, "is not a normal cat."

"With cats, what's normal? You've read about cats who have wakened the family during a fire. And about the cats in San Francisco that alerted their households before the 1906 quake."

"But that's…"

"Of course a cat can feel the temblors long before people can. But, Clyde, it takes more than a dumb beast to want to alert his family. And what about the cat attack on a prowler? I read about that just a few months ago. Scratched the man so badly he ran out of the house, didn't steal a thing. And the cat that saved a baby from strangling by summoning the child's mother.

"They're all documented. As much as any report by a cat owner can be documented." She cut another slice of lemon cake for him, and filled his coffee cup.

"Look," he said, "this isn't just unusual behavior. Not like those examples. It's…"

"Impossible," she said, and shrugged. "What we need is more information. Before you think you've gone over the edge, let's see what we can find out."

He had not expected this reaction. He should have. Wilma was never one to let popular conceptions influence her. "And," she said, "if Joe Cat did phone you, if you aren't the butt of some joke-which of course is entirely possible-then maybe Joe's not alone."

"Not alone?"

"Why would he be the only cat with such talents?" "Are you thinking of Dulcie? But she…" "I don't know what I'm thinking. Let's go over to the library, see what we can learn. You're not going to find Joe until he wants to be found." "But Dulcie hasn't come home, either." "Let's go, Clyde. I worry about that cat too much. She's good at taking care of herself." She finished her coffee and cake, and rose.

Within ten minutes they were settled in the library reference room, and into the computer, pulling up references to cats in history, cats in folklore, cats in mythology. Within an hour they had begun to find unsettling references, tucked into more mundane material.

And then from the veterinary school at Davis they found several references to strange behavior in the feline.

Accessing the Internet, they printed out the pages. Wilma copied entries, as well, which were not strange in themselves but which might add to the overall picture. She was intrigued by articles on the building of the Panama Canal, when crates of alley cats had been imported by freighter to fight the overwhelming wharf rat population. She found similar references about the importation of stray cats to San Francisco during the gold rush, to control the rat infestation along the wharves. A local folklore of amazing cat stories had grown up, intertwined with gold rush tales.

Their research formed a disturbing fabric. Wilma was fascinated, as if their discoveries answered some urgent question of her own. He didn't realize the library was closing until the overhead lights began to go off, throwing the corners into darkness. "I thought they stayed open until nine."

"It is nine." She gave him an exhausted and satisfied smile, and began to collect their scattered copies. "I need a beer, I feel-shaky."

"I need three beers and a hamburger."

She brushed a fleck of computer paper from her sweatshirt. "Let's run by my place first. Just-to see if Dulcie's come home."

They retrieved Clyde's car from the library parking lot and swung by both houses. Neither Joe nor Dulcie had come home. Clyde fed his animals, and let them out for a few minutes, then they headed for Marlin's Grill. Driving slowly along the lit village streets past the few shops and galleries still open, past planters of flowers blooming beneath the reaching oaks, they watched for the two cats. Through the open car windows, the sea wind was damp and cool. They were quiet as they parked in front of Marlin's.

The grill's plain wood storefront made a stark contrast to the glittering glass and chrome high-tech gallery on its right, and to the used-brick building on the left, with its deep, flowered entry patio and exclusive decorator studio.

Marlin's Grill had no potted plants framing its door. No fresh, modern persona. It was dismally dated. Just a plain pine, 1950s exterior. And the interior was equally uninspired.

Marlin's was the product of a time when knotty pine paneling, inside and out, was big. The present management had seen no reason to change what had once been popular. Marlin's was possibly the only business establishment in Molena Point that was not regularly refurbished to a bright, exciting new interior. But who needed to redecorate, when the hamburgers were the best in town and the seven varieties of draft the best you could get anywhere on the coast.

Over the years, Marlin's yellow wood walls had darkened to the color of dead oak leaves. The leather upholstered booths were worn and cracked, but were deep, comfortable, and private. Clyde and Wilma sat at the back, away from the few other customers. They ordered an English dark draft, and rare burgers with onions and Roquefort.

When the Latin waiter had brought their beer and gone away, Wilma said, "Just before we left the library, when I went back to my office, Nina Lockhart told me that someone else has been interested in the material on cats."

"Oh? But not the kind of material we dug out."

"Exactly the same material. The same references."

Clyde watched her uneasily.

She said, "I remember the man, he came in late last week. I remember Nina helping him." She sipped her beer. "Nina pulled up the same entries we used. She brought him the same books." She set down her glass. "She plugged into the Internet, helped him copy the same pages we copied. I was working in a carrel across the room. I remember him because he seemed uncomfortable and hurried."

The soft overhead light brightened her steel-colored hair and the silver clip that held it. "He didn't notice me until around midmorning. But then, when he looked up and saw me, he looked shocked. Looked as if he knew me. He stared at me hard, then snatched up his copies and left."

Wilma sipped her beer. "He didn't finish copying the references Nina had set out, he just left."

"Who was he? Do you know him?"

"I've seen him around the village. I don't know who he is."

"He couldn't be an old parolee?"

"No." She laughed. "That man was never on my caseload."

"Did he check out books? His name would…"

"He didn't check out anything, just made copies. He didn't tell Nina his name, and he's not a regular patron. A thin man, tall and quite stooped. Light brown, straight hair down to his shoulders, muddy-looking eyes. Some kind of scars on his face and hands, covered over with flesh-colored makeup. Nina said it looked disgusting. He wore a tan windbreaker, tan cotton sport shirt, dirty white running shoes. Nina said he had a British accent. I could hear a little of it from where I sat. Lyrical-I'd say maybe Welsh-a poetic lilt. Charming, but amusing in such a dour man."

Clyde had set down his beer. "That was Lee Wark."
