“You’re the first one. O’Malley, do you know who Sir Isaac Newton was?”

“A scientist or somebody.”

“Both somebody and a scientist. For centuries, Newtonian physics gave science the tools it needed to build the modern world. Newton’s theories and methods still work, but we now know that many of them are incomplete or even wrong.”

“How can they work if they’re wrong?”

“It has to do with reductionist observation and the power of approximation in the reliability of short-term effect.”

“Well, of course,” O’Malley said, and rolled his eyes.

“Einstein destroyed Newton’s illusion of absolute space and time. Quantum theory put an end to the notion of a controllable measurement process.”

“How many beers have you had, Ed?”

“This all relates to something good that’s soon going to happen to you, O’Malley. You know Galileo?”

“Not personally.”

“Galileo was a great scientist, too, and one of his theories, related to the oscillation of a pendulum—that its period remains independent of its amplitude—is still taught in most high-school physics classes more than three hundred years later. But it’s wrong.”

“I’ll bet you know what’s wrong with it,” O’Malley said, as if he was humoring an eccentric.

“Everyone doing physics for the last thirty years knows it’s wrong, but it’s taught anyway. Galileo used linear equations. But turbulence is present in the system, so it requires a nonlinear approach. Chaos, O’Malley. Underlying even the simple system of a pendulum is chaos, potential for complex and unexpected behavior. Now, I’m going to give you something.”

“What I need are the magic words to make Lianne forgive me.”

“Life can sometimes seem hopelessly complex, unpredictable, chaotic. Then a strange order makes itself known. You tell Lianne what you’ve done and what I’ve done, so she’ll know there’s order in the chaos. But first, cash these and take the money home to her.”

From a pocket of his white sport coat, Lamar extracted seventeen chips worth seventeen thousand dollars and put them on the bar.

The snowy pair glided across the moon-chilled yard: clearly seen but not in detail, catlike, wolflike, yet little resembling either cats or wolves, both familiar and strange, dreamlike.

When the animals arced toward the house, disappearing around the north end of the porch, Grady hurried from the kitchen, navigating by the LED numbers in the oven clock and by the hum of the refrigerator.

Blind in the windowless hallway, he felt along the left wall until he found a door.

In his study, two pale rectangles silvered the darkness directly opposite the entrance. His familiarity with the furniture arrangement allowed him to make his way quickly toward those undraped windows.

Halfway across the room, he gasped as a figure loomed against one of the framed panels of moonlight. But at once he realized that it was Merlin, on this side of the glass, paws on the sill. Grady went to the other window.

The night remained for a moment as night had been for millennia: full of myth, mystery, and threat, but in fact less dangerous than the day, if only because more men were sleeping now than would be sleeping after dawn. The venerable stars. The ancient moon. The old Earth, its timeworn beauty under wraps until sunrise …

Then suddenly the night was new, as the white enigmas appeared. Having been out of sight, tight against the house, directly under the windows, they raced away from the building, past the trunk of the birch, north across the lawn. They halted at the limit of visibility, faint featureless presences, huddling together as if conferring.

Panting agitatedly, beating his forepaws against the windowsill, the wolfhound wanted to be in the night and in pursuit.

“Settle,” Grady said, and again, “settle.” A third issuance of the command was required when always before one had calmed the dog.

Out of the darkness, the visitors returned, not directly but obliquely, angling east toward the front of the house.

Dropping to the floor, beyond the rays of the moonlamp, Merlin became a disembodied presence, a canine poltergeist, knocking across the floorboards, rapping the furniture and the doorjamb with an ectoplasmic tail, abandoning the study for a different haunt.

With the windows at his back, Grady was a blind man all the way across the room, reaching with both hands for the doorway. In the hall, he slid one palm along a wall until he reached the living room.

Already Merlin had materialized at a front window to the right of the door, paws on the sill.

Making his way toward the window to the left of the door, Grady bumped an end table. He heard a lamp wobbling, found it, steadied it.

Earlier, when he opened all the draperies and shades, he hadn’t imagined chasing around the house in pursuit of circling visitors. He merely wanted to have immediate access to any window that gave a view of an area where a noise might arise or entry might be attempted.

By the time he reached the window, he began to suspect that these mysterious animals were as curious about him as he was about them, that they were intent on satisfying that curiosity.

Beyond the porch, east of the house, lay the front yard, part of it overlaid with a faint tracery of moonshadows cast by the intricate branches of the huge birch tree.

The visitors were not on the yard or on that portion of the county lane—Cracker’s Drive—visible from this vantage point.

Nothing else traveled the night, either. No deer were present, though they frequently came to graze upon the lawn. Often coyotes whidded through the lunar glade, all legs and haunches and sharp shoulders, but on this occasion, they were hunting elsewhere.

As though aware of their audience and timing their entrance for maximum drama, the creatures sprang as one over the railing at the north side of the porch, seemed to cross the deck as fast as two pulses of light, and vanished over the railing at the south end.

The speed with which they moved and the darkness of the porch prevented Grady from learning anything more significant about their appearance than he had perceived from a distance in the meadow. He confirmed their size and their nimbleness, and thought he had seen lushly plumed tails, but their faces remained unrevealed.

They ran on all fours, though it seemed that they reared up as they approached the south end of the porch, that they took the last few steps on their hind feet before vaulting over the railing. Their movement wasn’t what he expected of any four-legged mammal in these mountains, though he couldn’t precisely identify the difference.

The instant the creatures leaped out of sight, Merlin abandoned his post and hurried unerringly through the dark living room to the hallway. Most likely, the wolfhound intended to track the animals from one of the library windows at the south side of the house.

Grady was so sure these visitors were intrigued by him and intent upon him that he saw no reason to scramble after them through the gloom, at the risk of falling and breaking a bone. They weren’t going to retreat into the mountains and leave him forever wondering about their nature. They had initiated a process of discovery, and they were not likely to relent from it.

This was an extraordinary expectation. Wild animals were by their nature wary. Even confident predators like mountain lions generally slunk away into the brush at the sight of a human being.

In this wooded vastness, only bears were fearless. An eight-hundred-pound brown bear was as ready to charge a man as to ignore him.

Grady felt his way cautiously through the living room, from sofa to armchair to armchair, and as he reached the hallway, he heard a thin cry of doggy excitement.

The moth danced with the false flame of the ceiling light, and its shadow swelled and shrank across the pages of the books through which Cammy Rivers searched for answers.

The horses and other animals at High Meadows Farm had seemed no worse for the time they spent in a trance, if indeed it was a trance. But such behavior surely must be symptomatic of a physical disorder.

In her apartment kitchen, above the veterinary clinic, the table was stacked with reference volumes that had thus far failed her. The Internet had failed her, as well, so she put aside one book and opened another to its index.
