Unfortunately, when Anna reached him, Roxbury was on a cellular phone in a Jeep on BLM land adjacent to the park. His cure for the crazies had been to throw himself into his work. Their phone connection started out bad and rapidly went to worse. The last intelligible words were mutually desperate promises to get in touch.

Dead ends.

That was when, faced with an afternoon basking in Dottie Dierkz's grief, Anna had decided to hang on to the borrowed sedan a few more hours and call on the Tillmans. She didn't phone ahead for the obvious reason that she didn't want to be told not to come and thus have an honorable avenue of escape denied her.

Holden and his wife lived in a modest house on the outskirts of the town of Carlsbad. Outbuildings, a requisite in the West, cluttered the lot beside and behind the house: an old garage with a door that wouldn't close, two trucks, a horse trailer with one flat tire, a barn with a horse without sense enough to get in out of the rain standing miserably nearby, and a dog house, sans dog, with a peeling tar-paper roof. Other items scattered around completed a look that Anna, through long familiarity, had come to find homey. Rubber tires, a staple of western decor, were tumbled near the woodpile; an aluminum canoe, partly filled with brackish water, was grounded under a leafless tree.

She parked the sedan in front of a picket fence denuded of paint by wind-blown sand and let herself through the gate. The tiny porch was overflowing with cowboy detritus: deer antlers, rusting metal pieces of machinery that, like bleached skulls and pine cones, created their own artistic statement. To one side of the door a square picture window framed a book-covered table lit by a single lamp. On such a gray day, the golden glow was welcoming. Anna was glad she'd come.

The door was opened before her knuckles could fall a second time. A woman a good ten or fifteen years Holden's junior smiled at her with the hushed apologetic look that unmistakably says "nap time." Anna had forgotten the Tillmans' four-year-old. Waking the boy was a sin on two counts, once against the child and once against his mom. Anna found herself whispering.

Holden was napping as well. He and Andrew were curled up together on the boy's little bed. Anna was warmed by a glimpse of them as Rhonda Tillman closed the door off the kitchen.

Tillman's wife was classically beautiful, with thick lustrous hair that fell past her shoulders and wide-set green eyes under winged brows that had probably never known a pair of tweezers. She was model thin, with long slender arms and tapered fingers. When she talked her hands sketched graceful pictures in the air to accompany her words. Holden's wife was young enough and pretty enough to dislike on sight, but she gave Anna two homemade oatmeal cookies and a glass of white Zinfandel so Anna decided to overlook her faults.

Rhonda pushed aside a paper plate full of multicolored Play-Doh and put her elbows on the painted wood of the kitchen table. "Holden's driving me nuts," she said, and she and Anna fell into the easy camaraderie women often do when left to themselves. "I thought I was going to have to wrap him in a towel and shove the painkillers down his throat the way I do with the cats."

Anna broke off a chunk of cookie and washed it down with the wine. Beer last night, wine now. Two years of abstinence poured away. She just didn't give a damn. The terrors of the bottle had faded, the attendant weirdness an unreal memory. Not to mention, the stuff didn't seem to work anymore. Three beers had left her with a full bladder and no buzz. Still, she drank Rhonda's Zinfandel, was eager to drink it. A memory of comfort? Of forgetfulness? Maybe it was the only way she knew of handling death. Nobody important had kicked the bucket in a long time. No wonder sobriety had been a piece of cake.

"How's Holden doing?" Anna asked, tired of asking the same thing of herself.

"Not good," Rhonda replied in her hushed nap-time voice. The softness made Anna lean across the table, her and Rhonda's heads together like conspirators. It was a nice feeling. Rhonda picked up a cookie with both hands, holding it between fingertips and thumbs as if it were a sandwich. Nibbling around the edge with little squirrel bites, she thought about her husband. "Very bad, in fact," she said at last. "He's convinced himself he killed Frieda Dierkz. Now he's working on convincing himself he can't trust his own decisions. This morning he had Andrew in fits dithering about whether to let the little guy ride in the front seat. Poor old Holden. I can read him like a book. No, like a newspaper. His emotions are headlines. He was scared he'd crash the car, hurt Andrew." She took a delicate sip of wine and resumed torturing her cookie to death.

"'Tain't so," Anna said. "That's not how it happened." She decided now was not the time for secrecy. "Did he tell you what I found?"

Rhonda nodded, her hair shining in the overhead light. "Holden no longer believes in your butt-print," she said. "It's like he won't let himself believe. Some sort of punishment. He said he would have known if somebody had gone up there."

"No, he wouldn't have," Anna argued. "Sixty feet above him, in the blackety-black of that frigging cave, Godzilla and Puff the Magic Dragon could have been perched up there the whole time and none of us would have seen them."

"Not seen," Rhonda said. "Known. He's getting metaphysical in his delusions."

"Damn it." Anna was annoyed. "It was my butt-print. I saw it. I should know. It was there. I could see pocket seams. It was an ideal, perfect, unassailable butt-print."

"Talk to him?" Rhonda asked.

"Sure."

"It won't do any good."

"Probably not." They sat in companionable silence for a while. A fat white cat with Siamese markings from one ancestor cut into tiger rings from another jumped up on the table and stretched out full length, his paws pushing gently against the base of Anna's glass.

"You know you're not allowed on the table when we have company," Rhonda said. The cat twitched its tail in disdain.

"Are you a caver?" Anna asked.

"I used to be. Not so much anymore. When you're married to the Holden Tillman it gets old." There was a tinge of bitterness there, but Anna knew the feeling. Some battles weren't worth fighting. "I still do some," Rhonda said in self-defense. "I just backed out of the whole political side of it."

Anna had not considered caving as having a political side. Naive of her; everything touched by humans was touched by politics. "How so?" she asked to keep the visit from ending.

"I used to go to all the grotto meetings. Get involved in all that. My last year I was president of the local grotto. No more."

Grottos. Local groups of cavers. That was the key. Anna had overlooked the inevitable: people couldn't resist joining up and forming clubs. Cavers were no different. She could let the AMA and the PTA alone. "Grotto meetings!" she said as one might say "Eureka!" "Is Brent Roxbury a member? Is Zeddie?"

"Are you going to help Holden?"

Anna laughed. "Unless he really did kill Frieda."

"Not a problem. Holden hasn't killed anybody in years. He puts spiders outside. Even big hairy ones." Rhonda got more cookies from a jar on the counter and refilled their wineglasses. "Fire away."

Anna outlined her theories. It didn't take long. If someone had attempted to kill, then finally had succeeded in killing Frieda, the list of suspects was mercifully short: the members of the core group with the exception of Oscar, Holden, and herself. If the fall in the Pigtail was unrelated to the rock that had broken Frieda's leg, then they were all suspects. Anna felt duty-bound to mention that but didn't give it much credence. The law of averages was meant to be broken, but it served as a fairly trustworthy guide.
