In the windless night, the lower branches of the lacy birch first tossed but then merely trembled as the principal agitation shifted to higher realms. As something ascended, the tree opened its autumn purse and paid out a wealth of leaves.

Grady disengaged the window lock, but before he could raise the lower sash, the climbers sprang from tree to house roof: one thud, immediately another. Judging by their footfalls, they seemed to be exploring this way and that, up the slate slope toward the ridgeline.

Paws still on the windowsill, Merlin tipped his head back to stare at the ceiling.

“Maybe raccoons,” Grady said.

Snorting dismissively, the wolfhound dropped from the window, turned toward the bedroom, and cocked his head to listen.

The master-bedroom fireplace stood directly above the fireplace in the living room. A metallic rattle and creak echoed down the shared flue, drawing Merlin to the hearth.

Something on the roof was testing the copper spark-arresting hood atop the chimney. Having installed it himself, Grady knew that it couldn’t be easily removed.

Because no fire currently burned, the damper was engaged between the smoke chamber and the firebox. If something got into the flue, it could not penetrate the steel-plate damper and enter the bedroom.

Abandoning the chimney hood, the roof-travelers scurried down the west slope.

As the noises faded toward the back of the house, Merlin hurried out of the bedroom. Grady reached the top of the stairs just as the wolfhound arrived at the bottom.

Descending, he wondered if he had locked the back door after they had come in from the dog’s late-afternoon exercise. Then he wondered why he was apprehensive.

He could not deny that something less than fear but more than mere disquiet gripped him as he sought Merlin through the first floor and found him in the kitchen. The dog stood at the door. He wanted to go outside.

Grady hesitated.

The potatoes were stored in a walk-in room within the windowless cellar, behind a stout oak door with iron hardware, as if they were a treasure worth guarding.

Deep shelves lined the smaller room. On the shelves were many well-ventilated baskets that each contained three layers of spuds.

The highest shelves held only a few baskets. Standing on a step stool, Henry Rouvroy put the two suitcases full of currency on a top shelf, flat on their sides and against the wall.

After climbing off the stool, he could not see the precious luggage overhead. He returned to the kitchen. In a day or two, he would find another and better hiding place for the money.

Because he didn’t care for potatoes, he would throw away that starch stash and rip out the shelves. Properly refitted, the potato cellar would be an excellent place to keep a woman when eventually he got one.

In Jim and Nora’s bedroom, he selected underwear, socks, jeans, a flannel shirt, and work boots from Jim’s limited wardrobe. Although Henry was less work-toned than his twin brother, everything fit him.

The shirt was from Walmart, not from L.L. Bean. The jeans were cut for working and for horseback-riding, not for Sunday in the park. The boots had no style whatsoever. The disguise was perfect, but for a moment he felt displaced, cast down from his rightful position.

Leaving his shoulder rig and pistol on the bed with a spare magazine of ammunition, he wrapped his expensive clothes and shoes in the shirt that he had been wearing, and tied everything together with the sleeves. He would bury those garments in the grave with his brother and sister-in-law.

Posing in front of a free-standing mirror, Henry addressed his reflection: “Look at you, Jim-back from the dead.”

To his ear, at least, he sounded like his brother.

If those who knew Henry in his former life could see him now, they would not recognize him. The clothes alone would ensure that they looked through rather than at him. He could pass for a hick from fly-over country, with whom they had nothing in common except that they, too, were born of man and woman.

In the kitchen, at the sink, he gathered up the potatoes that Nora had been peeling, and he tossed them in the trash can.

After examining the contents of the pantry and refrigerator, Henry found excellent sausages, acceptable cheeses, fresh eggs, a jar of red peppers, and an unfortunate but edible loaf of white bread made of flour so bleached that it glowed as if radioactive.

He opened three different Cabernet Sauvignons, none known to him. Only the third proved drinkable. If this was the best wine that Jim and Nora could afford or, worse, if this was their idea of a good wine-well, sadly, then they were better off dead.

Henry planned to spend two weeks laying in a three-year supply of canned and packaged food. He hoped that somewhere in a hundred-mile radius would be a specialty grocer and spirits vendor offering a sophisticated selection of consumables of the quality to which he had long been accustomed.

Withdrawing from the world for three years would be an endurable hardship if he was provisioned with canned breast of pheasant, beluga caviar, hearts of palm, vintage balsamic vinegar, and scores of other delectable items that made the difference between living and merely existing.

After dinner, he washed the dishes. This was an annoyance that he would have to tolerate until he found a woman to keep in the potato cellar.

In his elegant townhouse at the farther end of the country, he had employed a housekeeper, but she’d received a salary and benefits. And she had not been the kind of woman who excited lust.

A windowless potato cellar made it possible not only to have the services of a housekeeper without the expense, but also to enjoy sex without the tedious process of seduction and without the tiresome pillow talk women expected afterward. Thus far he could see no other advantage that, in normal times, this crude residence had over his city digs; but normal times or not, a potato cellar might eventually prove to be a more desirable amenity than a home theater and a sauna combined.

Normal times. In spite of having risen before dawn, having driven for hours, having killed for the first time and the second time in his life, and even in spite of having prepared his own dinner, Henry Rouvroy was not sleepy, not even weary. Being aware of the chaos that would sweep the nation in the months ahead, he was motivated to begin at once to prepare this house to meet his needs in these abnormal times.

After a brief hesitation, Grady opened the kitchen door and followed Merlin onto the porch. Scatters of dry birch leaves crunched underfoot.

No further sounds came from the roof, and the moonglow revealed no visitors on the porch or on the immediate lawn.

The taller dry grass beyond the mown yard appeared to curl like a line of phosphorescent surf breaking on a dark shore.

Screened by trees and swallowed by distance, the lights of the nearest neighbors could not be seen.

The workshop in which he crafted furniture, an add-on to the garage, stood forty feet south of the house. Those windows were as luminous as the panes of a lantern.

Grady had concluded his day’s work before going on the hike with Merlin. He remained certain that he had left the workshop dark.

Something drew the wolfhound toward that building.

Few crimes occurred in this remote land, and those were mostly crimes of passion, seldom theft or vandalism. Consequently, Grady occasionally forgot to lock the workshop door.

He might have forgotten this time, but he hadn’t left the door open, as it now stood. With the faintest click of claws, Merlin preceded his master across the threshold.

Because fluorescent light created little or no shadow, making it difficult to judge depth and to assess surface textures of materials being worked, pendant fixtures with shallow hoods brightened the room. The fixed machinery was lit from every angle to avoid harsh shadows, so that moving parts clearly could be seen to be moving.
