Heaven and Earth by Nora Roberts

quite clear, that slithered around the edges of home. But it didn’t come from MacAllister Booke.
    She drew away, picked up her tea again. “In fact, I may agree to talk to him myself. Fifty dollars an hour.” She let out a low, delighted laugh. “Fascinating.”

    Loaded down with portable equipment, Mac plowed through the snow piled on the floor of the narrow forest beside his cottage. The police report and the newspaper stories he’d read cited this as the place Nell had run to when Evan Remington attacked her and Zack Todd.
    He’d already completed scans of the kitchen area, the site of the attack. He’d found no negative energy there, no remnants of violence. Which had surprised him until he’d reasoned out that either Nell or Mia would have cleansed the house.
    He hoped to find something in the woods.
    The air was still and cold. Ice gleamed on the dark trunks and branches of trees. Snow lay on them like fur.
    He saw, and was charmed by, what he recognized asdeer tracks, and automatically checked his camera to be certain he’d loaded film.
    He passed a little brook where trickles of water forced their way over rocks and ice. Though his gauges didn’t register any anomaly, he felt something. It took him a moment to realize it was simply peace. Simply pleasure.
    A bird called, flashed by like a bullet. Mac just stood, happy and content. It felt good here, he thought. A place where the mind could be quiet. A place for picnics or contemplation.
    With some reluctance, he continued to walk, but promised himself he would come back and just enjoy.
    He wandered, and though he hated to spoil the mood, he tried to imagine what it had been like to run, fleeing in the dark from a man bent on violence. A man armed with a knife already bloody.
    Bastard, he thought. The bastard had hunted her down. A rabid wolf after a doe. Because he could. Because he would rather have seen her dead than free of him. Prepared to swipe the knife over her throat rather than lose what he considered his possession.
    Fury raged in him, hot, roiling fury. He could almost smell the blood, the hate. The fear. Steeped in it, he needed several moments to realize that his sensors were going wild.
    “Jesus!” He jolted back, shook himself, and was abruptly the cool-headed scientist again.
    “Here. Right here.”
    He swept with scanners, dragging out his tape recorder, muttering data into it. He paced off the area, using another gauge to measure distance, radius, diameter. Down on his knees in the snow, he recorded, calculated, documented. Considered, while the numbers and needles on his tools swung wildly.
    “Highest charge, almost pure positive energy encompasses an area of twelve feet, in a perfect circle. Most rites of paranormal origin involve protective circles. This is the most powerful I’ve found.”
    Pocketing his tools, he used his hands to dig, to clear. A light sweat covered his back before he uncovered a reasonable portion of the energy circle.
    “There are no markings under the snow. No symbols. I’ll need to come back with a shovel to clear the entire circle. If this was made on the night Evan Remington was arrested, it was cast more than two months ago and would have been ritualistically closed on that same night. Yet there is a positive echo registering a steady six-point-two on my scale.”
    Six-point-two! His mind leaped at the data. Hot dog!
    “My previous experience, with an active circle during an initiation rite, registered no more than five-eight. Check those data.”
    He got to his feet again, snow clinging everywhere as he took photographs. He dropped his tape recorder, cursed, and spent some time scooping it out of a pile of snow, then worrying that he’d damaged it.
    But nothing could diminish the thrill. He stood in the silent wood and wondered if he had stumbled across the heart of the Sisters.

    An hour later, without bothering to go back to the cottage, Mac was trudging along the snowy beach. The tide had moved
