On the Prowl

moving.”
    “I need to stretch first.” Stretching helped with lactic acid buildup in taxed muscles, making them less likely to stiffen. It would also give her a few minutes to locate her brain, which had to be around here someplace.
    Kai untied the jacket she’d fastened around her waist, shrugged it on, and moved to the curb so she could stretch her hamstrings. “So why did you track me down?” Automatically she reached for his shoulder to balance herself. This kind of touching they’d done often.
    “I need to let you know about the killer.”
    “What about him?” She dropped her heels off the curb. “Or it.”
    “It may be a chameleon.”
    “You’re not talking about a cute little lizard that changes color.”
    “No, this creature changes its form entirely, not just its color. Chameleon is the closest word in English.”
    “Not the illusion of change? It really changes?”
    “Yes. Mass is preserved, as is the essential brain composition and metabolism. They can look like anything, though, and unlike demons, they change quickly if they have a good pattern for the new shape.”
    “Scary.” She switched positions, this time pulling her knee to her chest to stretch her quads.
    He was looking at her legs. He never looked at her legs, not that way. “I wanted you to be watching for something that seems human, but isn’t. You’ll be able to tell from the way its thoughts look, won’t you?”
    She nodded, a frown pleating her forehead. “You have any reason to think I’m likely to run into this creature?”
    “Not exactly.”
    “You aren’t giving me a warm, fuzzy feeling. And what about you?” She started back at an easy jog. “Can it trick you?”
    He fell in beside her. “Since its metabolism doesn’t change, I’ll smell the truth if I’m close enough.”
    “But you’re not lupus.”
    This smile was amused. “No.”
    Personal questions amused him now, instead of making him run the other way? “Is that all you came here to tell me? To watch out for something like looks human, but isn’t?”
    He nodded. “I may have exaggerated the urgency. I think the killer is a chameleon—that fits what I know—but I’m not certain. They’re extremely rare, for one thing, and normally they exist only in high-magic realms.”
    “Is that where you come from? A high-magic realm?”
    “Yes.”
    Another answer, offered as easily as if his true nature wasn’t a big, fat secret.
    He added, “Not the realm where chameleons are found, though. They’re constructs. That’s not allowed in…my home realm.”
    “Constructs.”
    “Made, not born.”
    “But—but how could that be possible?”
    “As I understand it, the mage—no, it would have to be an adept. He or she would start with—”
    “Hold on. There really are mages and adepts? I thought that was just myth, like unicorns or…never mind.” She’d been about to say “or dragons,” but they’d turned out to be real.
    “Unicorns are real, too. Or mostly real. They don’t exactly live in any of the realms, but…wait, wait.” He held up a hand, forestalling the questions hovering on her tongue. “I’ll explain another time, or try to. I don’t understand unicorns myself. For now, accept that if this creature is a chameleon, it’s extremely dangerous and may be drawn to those with a strong Gift.”
    They jogged together quietly after that. Kai was comfortable with the lack of speech; the companionship of silence reminded her of her grandfather, who could go days without using more than a handful of words, but was so present he made conversation with a glance or a gesture.
    Nathan was present in much the same way. Last night and today, though, he’d dipped often into words, telling her more about himself than he’d ever revealed in one gulp. Yet much of him remained hints and questions, with a few facts swirling around in the mist.
    Fact: He lived longer than humans. A lot longer. She’d learned that a few months ago when they were watching the History Channel and he commented on something that happened in the First World War—something he’d experienced. Fact: He healed fast, faster than she’d have believed possible if she hadn’t seen it herself last night. Fact: He came from another realm…and oh, but she’d done a good job of pretending her mind wasn’t blown by that news. There were stories of other realms, sure, but whatever reality lay behind those tales had been lost or obscured in their telling and retelling
