“Since we knew what diving was about. Since the Three Sisters were in pinafores. Since we quit fucking around,” Holly said sharply. “Always.”

Anna waited but there was no more. Denny came back with the salad and, seeming to take it for granted that he was to wait on them, cleared Anna’s desk and set out plates and flatware. Anna was too tired to help and Hawk and Holly seemed determined to let him serve. When he was finished, he sat down on a stool he’d pulled up. He was the only one at the table, the only one interested, it seemed, in the food.

“This is a celebration,” he said, looking not at them but down at his empty plate. “I’m getting married tomorrow.”

“To a regular woman?” Anna asked, taken by surprise.

Holly began to laugh.

Hawk turned his face away from Denny, from his sister. There was as much pain in his look as there had been in Holly’s laughter.

Anna stood, drained her glass, shook off their misery. She was tired. She was hungry. Maybe they’d been on one too many dives. The deep addled people’s brains. She carried her wine bottle to the desk and sat down in the wooden swivel chair. Supper was made and it was free.

“Congratulations, Denny,” she said equitably. “Please pass the salad.”

Mist lay over Amygdaloid Channel. Humps of pale gray moved lazily over the surface as if ghostly whales swam between air and water. Patches drifted clear and the silver of reflected light glowed till fingers of fog curled back to reclaim the space. To the east, over the green ridges of Belle Isle, the dawn sky was burning into blue, the promise of a beautiful day.

Wrapped against the chill that the forty-eighth parallel would not relinquish even in June, Anna sat on the front steps of the ranger station. Cloaked in a shapeless plaid flannel bathrobe, the tail tucked under her feet to keep them from the dew-bitten planks, she stared through binoculars at the far shore: a thin line of sand and stone, now revealed, now shrouded by the mist. Beside her a mug of coffee curled tiny tendrils of fog into the cold air; a minuscule offering to the gods of the lake.

“Come on,” Anna said softly. “Come out. I know you’re there. And I know you’ve got the baby. Show yourselves.”

From the silence of the channel a loon called and was answered. The sun pierced the pines on the cliff’s top and dyed the mist rose. Open water glittered, bright as new pennies. Again the loon called its haunting liquid warble, this time to be answered by the sound of wings on water.

Now they’ll come, Anna thought. “I’ve seen your tracks,” she whispered. “I know you’re there.”

A shadowy red form darted between her and the dock where gently rocking boats cradled fishermen. She refocused the glasses. The black muzzle of a little fox came into view. Head tilted to one side, pink tongue lolling, she sat less than twenty feet from the station steps ready to beg for her breakfast like a house dog. “Not you, Knucklehead,” Anna murmured and again trained the field glasses on the opposite shore.

Somewhere to the north a power boat growled to life and morning’s spell was broken. Now they wouldn’t come. “Damn.” Anna lowered the binoculars. Isle Royale’s wolves were the shyest of creatures. Some rangers who’d worked the island for years had never so much as glimpsed them. Scat, tracks, howling, confused reports from hikers startled by foxes-that was all most people ever knew of the wolves in summer.

In winter, when the island’s dense foliage dropped its leaves and deep snow made tracking easy, a Winter Study Team came to ISRO-Park Service shorthand for Isle Royale-for several weeks and studied the wolf packs. Only two packs remained, twelve wolves in all, with only one new birth in the past year. The wolves were dying and the scientists didn’t know why. There was some indication that an outbreak of canine parvovirus, a disease carried by domestic dogs, was a factor in the decline, but inbreeding was the guess most favored at the moment.

The Park Service was doing all it could to preserve the wolves, even to the extremely unpopular extent of denying visitors and staff the privilege of bringing their pets to the island-or even within the park’s boundaries four and a half miles out. Still, the wolves did not thrive, did not reproduce.

At least it’s not us killing them, not directly, Anna thought, and enjoyed the sense of being one of the good guys, a compatriot instead of a despoiler. It was a proud feeling. And rare as hen’s teeth, added her mind’s resident cynic.

“Tomorrow,” she said to the empty stretch of beach across the channel. “At dawn. Be there or be square. And bring the puppy.”

The roar of the motorboat grew louder, wrecking what remained of tranquillity. A glossy wine-colored bow plowed up the mist in the channel. Anna gathered up her cup and crept back inside. It wouldn’t do for the public to catch the ranger in her pajamas. Besides, it was her lieu day. If she didn’t escape before a tourist happened to her, she’d undoubtedly get roped into some task for which the NPS wouldn’t pay overtime.

During the six months the park was staffed, Lucas Vega frowned on rangers leaving the island on their days off. Superior’s sudden storms had a habit of turning weekends into paid vacations. Consequently, Anna spent a goodly number of her days off selling fishing licenses, cutting fishhooks out of fingers, and listening to fish stories.

“Attitude, Anna, attitude,” she chided herself as she dragged on long underwear and polypropylene trousers, but she had every intention of escaping out the back door unless the approaching vessel could prove problems of a life-and-death nature.

This Tuesday and Wednesday, she’d promised herself a kayak trip, dinner at the lodge, and a phone call to New York. The trip would mix business with pleasure. Anna packed a tent and backcountry gear for several nights out. On the way back, she would spend a couple of days checking the more remote campsites.

The sun was high by the time she shoved off. By Anna’s standards it never got warm-not the deep bone-warming temperatures that baked the poisons out down in the Trans-Pecos-but the weather held jewel-bright. A breeze cooled by thirty-nine-degree waters cut across the bow when she nosed her sea kayak into the open water around Blake’s Point at the island’s northernmost tip, and even through the insulating layers her butt was cold. Hard paddling kept her from feeling the worst of the chill.

Waves, dangerous near the point where shoals broke them, rolled gently half a mile out. Anna kept her bow pointed into the swells and reveled in the sense of being part of the lake instead of a motorized nuisance, a noisy intruder it would shrug from its skin as a horse would twitch free of a fly.

Northeast was Passage Island with its historic lighthouse. To the south long fingers of land, rock shredded by fifteen centuries of a glacier’s feints and retreats, reached into the lake. In the spring sunshine, the peninsulas were clothed in rich greens and the water in the coves was tropical blue. Gold-colored stone, broken into blocks ten and twenty feet on a side, glimmered through the crystal water. Timber, blown over from the mainland or toppled from ISRO’s own shores, was scattered like jackstraws on the lake bottom. In places the fissured rock and bleached wood gave the disconcerting illusion of sunken ruins. Castles filled only with fishes, turrets pulled down to make playgrounds for otters.

Anna let the kayak drift down the sheltered channel beside Porter’s Island. Shipping her paddles, she ate a lunch of tortillas and beans. Lying back, her legs free of the enclosed bow, she let the sun paint patterns on her eyelids, as the water tapped its music against the sides of the boat.

When she finally paddled into the wake-riddled bustle of Rock Harbor, it was after five o’clock.
