She belted the radio on and, looking only where she put her hands, began to climb. Daggers of agave, needle-sharp and thrusting knife-like up from the rocky soil, catclaw in a bushy haze of tangled branches and small hooked spines, and jagged-toothed sotol, the black sheep of the lily family, tore at her skin and clothing. These dragons of this tiny Eden were the reason it had yet to be trammeled by humanity in the form of coolers full of beer and sunbathers slathered with cocoa butter.

Forty or fifty yards above the canyon bottom, Anna found a secure niche between a rock and a stunted yucca clinging determinedly to the thin layer of soil. "Three-eleven, three-one-five," she repeated. This time there was the reassuring static surge of the radio transmission hitting the repeater on Bush Mountain.

"Three-eleven," came Paul Decker's familiar voice.

Much to her surprise, Anna began to cry. The relief of that comforting sound had momentarily undone her. Paul, the Frijole District Ranger, always answered. Always. On-duty or off. There was even a radio in his bathroom.

"Paul, Anna," she said unnecessarily, giving herself time. "I'm about an hour north of where Middle and North McKittrick fork. We've had an… incident. I'll need a litter and enough people to carry it out." She knew better than to hope for a helicopter. The nearest was in El Paso, two hours away. A body-basket could be dropped down from a helicopter but it would take a very long line; dangerous in such treacherous country. Never risk the living for the dead.

"The victim is…" Is what? Anna's mind raced for the radio-approved double talk for "dead." "Dispatched" was the word of choice when a ranger had had to kill a creature- human or otherwise. But an already dispatched ranger being consumed by turkey vultures? "The victim is non-salvageable," she said, falling back on her ambulance triage protocol.

An alarming silence followed. "Paul, do you copy?" she asked anxiously.

"Ten-four," came the automatic reply. Then: "Anna, it's too late to get anyone up to you tonight. Can you hang in there till morning?"

Anna said yes and three-one-five clear. Wishing there was more to say, wishing the tenuous contact could be prolonged, she dropped her radio back into its leather holster.

At first light Paul would start out. In her mind's ear she could hear him digging his Search and Rescue kit out of the hall closet. Probably he would sleep as little as she did. He was that sort of man. Once, when alcohol and memories had kept her up late, she'd seen him creeping out of his house at three a.m. to count vehicles; making sure all his little seasonal employees had made it out of the high country and were safe in their beds.

Anna breathed deeply and leaned back against the pitted stone. At this height there was still sun to the west. Rich and red, it slipped toward Guadalupe Peak, the highest point in Texas. Texans, Anna thought, though she loved them with a pinch of salt and a lot of laughter, were full of shit. But when it came to the sky, they weren't just whistling Dixie. The Texas sky was something else. Sunsets of gold and crimson, stars to dazzle, clouds taller than the fabled Stetsons.

Thunderclouds were beginning to build to the north and west. There'd been lightning the previous night over Dog Canyon. Anna had watched it from her camp on the ridge between Dog and Middle McKittrick. It was the first storm of the season-all lightning and no precipitation. The weather pattern would continue that way till the rains came in July. Fire danger was high. Already fires burned half a dozen places in New Mexico and Arizona. Everyone in the park was on the lookout for smokes.

Red-gold fingers of light reached through the dry thunderheads, touching the desert with the illusion of living green-a green that would come with the monsoons.

"Seven-two-four Echo is ten-seven." The baby voice of the Carlsbad Caverns dispatcher startled Anna back from the clean peace of the sky. Carlsbad was going out of service late; leaving the cave with the bats.

Fortunately, there was still plenty of light to work her way down to the creekbed. She had no food for supper but something had spoiled her appetite anyway.

Down was worse than up. Gravity, eager to help, dragged at her every misstep. But she made it, stood solidly on the smooth limestone, water at her feet, a corpse in the saw grass. Anna tried to call the Dog Canyon Ranger to mind: Sheila Drury, 29?… 30?… 35?, female, Caucasian, park ranger, recently deceased.

The woman had entered on duty in December the year before. In the seven months since she had caused quite a stir. There'd been a lot of repercussions when she had proposed building recreational vehicle sites at Dog, and she'd raised a lot of fuss and furor over a plan to reintroduce prairie dogs into the area.

Politics and gossip were all that Anna knew of her. Dog Canyon District was two hours by car from the Frijole District. They'd never had an occasion to work together.

Too late to get to know her now, Anna thought dryly. Heaven and the vultures only knew what would be left come sunrise. Not for the first time, Anna wished she'd learned more natural history. Did vultures feed all night? Would she hear the grumbling, plucking sounds in the coming dark?

She dug her headlamp from her pack and pulled it tight across her brow. CLUES: that's what the law enforcement specialists at FLETC, the school in Georgia, had taught her to look for. CLUES: bloody fingerprints, cars parked in strange places, white powder trickling out of trunks. In the more populous parks like Glen Canyon and Yosemite, or those close to urban areas as were Joshua Tree or Smokey Mountains, crime was more prevalent. In fleeing Manhattan and her memories, Anna had kept to out-of-the-way places. So far all she'd had to deal with in the line of duty were dogs-off-leash and Boy Scouts camping out of bounds. Still and all, she was a Federally Commissioned Law Enforcement Officer. She would look for CLUES.

However nauseating.

ANNA fished two of the soggy lemon slices from her water bottle, mashed them to a pulp, and rubbed the pulp into her wet handkerchief. Tying it over her mouth and nose, she fervently hoped it would cut the stench of death down to a tolerable level.

Next she took the camera she'd been using on the lion transect and hung it around her neck. Switching on the headlamp, though it was not yet dark enough to do her much good, she waded into the saw grass.

The camera helped. It gave her distance. Through its lens she was able to see more clearly. Sheila Drury was parceled out into photographic units. As she clicked, Anna made mental notes: no scrapes, no bruises, no twisted limbs. Drury probably hadn't fallen.

Freaks of nature did happen now and then. Anna looked up at the cliff above, imagined Drury falling, dying instantly on impact: no contusions. Unlikely enough even if catclaw eight and ten feet high hadn't tangled close along the edge. Why would she fight cross-country through it in a full pack?

Anna turned her attention back to the corpse.

The skin of the face and arms was clear, smooth, the tongue unswollen. The Dog Canyon Ranger had not died of hunger, thirst, or exposure. Anna had more or less ruled those out anyway. Guadalupe Mountains National Park, though rugged and unforgiving, was barely twelve miles across. For a ranger familiar with the country to stay lost long enough to perish from the elements was highly improbable. Too, one presumed Drury had water, food-the stuff of survival-in her pack. A tent and sleeping bag were strapped on the outside.

No obvious powder burns, bullet holes, or stabbing wounds. Evidently the woman had not been waylaid by drug runners hiding in the wilderness.
