Miriam winced at the sudden stabbing in her head and pocketed the locket. Then she did what she’d planned all along: a three-sixty-degree scan that took in nothing but autumn trees and deadfall. Next, she planted her pack, transferred the pistol to her right hip pocket, retrieved her camera and the recorder, and started taking snapshots as she dictated a running commentary.

“The time by my watch is fourteen twelve hours. Precipitation is light and intermittent, cloud cover is about six-sevenths, wind out of the northwest and chilly, breeze of around five miles per hour. I think.”

Snap, snap, snap: The camera had room for a thousand or so shots before she’d have to change hard disks. She slung it around her neck and shouldered the pack again. With the Swiss army knife Ben had given her on their second wedding anniversary—an odd present from a clueless, cheating husband with no sense of the difference between jewelry and real life—she shaved a patch of bark above eye level on the four nearest trees, then fished around for some stones to pile precisely where she’d come through. (It wouldn’t do to go back only to come out in the middle of her own car. If that was possible, of course.)

As she worked, she had the most peculiar sensation: I’m on my second moon mission, she thought. Did any of the Apollo astronauts go to the moon more than once? Here she was, not going crazy, recording notes and taking photographs to document her exploration of this extraordinary place that simply wasn’t like home. Whatever “home” meant, now that gangsters had her number.

“I still don’t know why I’m here,” she recorded, “but I’ve got the same alarming prefrontal headache, mild hot and cold chills, probable elevated blood pressure as last time. Memo: Next time bring a sphygmomanometer; I want to monitor for malignant hypertension. And urine sample bottles.” The headache, she realized, was curiously similar to a hangover, itself caused by dehydration that triggered inflammation of the meninges. Miriam continued: “Query physiological responses to…whatever it is that I do. When I focus on the knot. Memo: Scan the locket, use Photoshop to rescale it and print it on paper, then see if the pattern works as a focus when I look at it on a clipboard. More work for next time.”
