Despite the steadily falling snow, Meg drove to the piano teacher’s with only half a mind on the road. Deidre, plugged into her MP3 player in the backseat, didn’t say a word until a quick “See ya later, Mom,” punctuated by a slamming door.

Now she had an hour to kill. Meg tried Linda one more time on her cell phone. The number rang and rang, until a recorded male voice clicked on.

“You’ve reached the home of Russ and Linda Van Alstyne. Leave a message.” Meg hung up. Without consciously deciding, she switched on her headlights and turned left out of the piano teacher’s driveway, headed toward the Van Alstynes’.

Linda lived on an old country road halfway between Millers Kill and Cossayuharie, dotted with houses that had been farms in the nineteenth century, widely spaced, with quarter-mile-long driveways. Good business for Meg’s son Quinn, who had kitted out his 200,000-mile pickup with a plow to earn extra money, but way too remote for Meg’s taste.

The Van Alstynes’ house was set back, high on a treeless rise that gave them sweeping views in the summer but looked desolate and wind-scoured in the winter. The long, long drive hadn’t been plowed anytime recently. Meg drove up as far as her Saab would take her, riding in the ruts left by the last vehicle to brave the hill, but around the halfway point she slowed, skidded, and slipped back several feet. Admitting defeat, she yanked on the parking brake and got out to walk the rest of the way.

Despite the gathering twilight, there weren’t any lights on that Meg could see. On the other hand, she would have to circle around to the west side of the house in order to spot the windows in Linda’s upstairs workshop. She banged on the mudroom door. No answer. Maybe Linda was out? Meg crossed the end of the drive and peered through the barn windows. No, there was her station wagon.

It was turning back toward the house that she noticed the odd blot in the snow near the doorway.
