Her spine barely hit the stairs, as far as she could see, and after two complete somersaults she landed, crouched, on her toes, hands spread and balance forward. Tony took his attention from the screen to stare at her. “How in hell did you do that?”

“Pure blind luck,” Margrit said, gaping at her image. The recorded Margrit whipped around and looked up the stairs, reminding them both what they were supposed to be watching.

The man was gone.

“Well, goddammit,” Tony said mildly, and leaned closer to study the other screens briefly. “I don’t see him. Rewind it.” He reached past her and punched the button himself.

In the rewind, as Margrit tumbled up the stairs, there was nothing, then a blur of blackness, and then the man in the space he’d occupied. “What the hell was that?” Tony played it forward, this time both of them watching the suspect.

Margrit threw the beer in his face. He doubled over again, falling into a crouch as he wiped his eyes frantically. His head wrenched to the side as Margrit stumbled, and he made one quick, aborted attempt to catch her, the movement so fast his image blurred again-white this time, the color of his shirt. He missed by a finger’s breadth, frustration contorting his features as he fell back into his crouched position.

Then all his energy seemed to rechannel. He uncoiled like a striking snake, the blur of black pixels that followed him expanding, curving around his body and shadowing him. A streak of brightness-the white of his shirt-etched a line through the blackness as it shot upward, off the top of the screen and out of sight.

“WHAT THE HELL was that? Rewind it! Rewind it!” Tony jabbed the rewind button hard enough to bruise his finger, swearing again as the tape zipped backward. The scene replayed itself while he leaned in, nose nearly touching the screen. “Where’d he go? Where’d he go?! Kid! Where’s the camera kid? What’s his name? Ira!”

“Boy,” Margrit said to the screen, all but under her breath. “And I thought my little acrobatic trick was showy.”

“That was impossible,” Tony snapped. “I don’t know what the hell happened there, but the video musta gotten screwed up. That just wasn’t possible. He couldn’t have jumped out of the viewing area, and where the hell’d he leap to? None of the other cameras show him landing anywhere. He’s gotta still be in the building. Gotta be.” His words fell over themselves even faster than usual, rising and falling nasal tones. Margrit found herself smiling at him. “What?” he demanded. “What’re you grinning at?”

“You’re cute when you’re upset,” she said. His jaw clamped shut and color scalded his cheekbones. The door opened with a bang and a sullen-looking Ira came in, dragging another chair.

“You’ve got lousy timing, Grit,” Tony muttered, before rounding on the security technician. “Where were you? Never mind. I need to look at every video in that room at-” He broke off to glower at the time stamp on the frozen video frame. “At 10:19 p.m. I gotta be able to see everything. Margrit.” Spoken with Brooklyn intensity, it came out Mahgrit. “I was gonna ask if I could give you a ride home, but there’s somethin’ weird goin’ on here. I donno how long this’s gonna take, and, well-” he forced a smile and slowed down his speech, accent thinning “-I don’t think there’s much you can do here.”

“Does that mean I’m dismissed, Detective?” Margrit ducked her head, feeling a faint smile of frustration pull at her mouth. The demarcation between her job and his had never seemed more vivid. Rationally, she understood, but emotion was more slippery. “Just when things are getting interesting.”

“Don’t be a pain in the ass, Grit. Not right now, okay?”

“Yeah. Whatever.” She heard the snappishness in her words and laughed, a sound of irritation rather than humor. She knotted her hand, trying to release ire before speaking again. “Look, I’m going to find Cole and Cam, and maybe we’ll keep hanging out. You’ll be able to find me if you need me to ID somebody, or something, all right?”

“Yeah.” Tony was already turning back to the video screens, forgetting Margrit was there. “Go have a good evening. I’ve got work to do.”

Rhythm pushed Margrit around the dance floor, until she was drifting like a leaf on a river’s surface. Strobe lights flashed and she lifted her hands into the air, weaving her arms together as sinuously as she could. The strobe chopped the motions into gorgeously inhuman pulses of motion, impossible to achieve in reality. Fog swirled above her, lit brilliant blue-white by the bursts of light. Steel girders threw soft-edged shadows against the dark paint of the ceiling high above. Stars, Margrit thought. The club needed to put tiny Christmas lights up there, to make stars against the ceiling. Buoyed by the music, she thought she might be able to break away and fly, if there were stars up above.

Dancers jostled around her. Margrit let herself be moved by them, feeling only distantly attached to her own body. Cole and Cameron had gone to the swing-dance room. Margrit, content to stay with the ever-changing music in the Blue Room, had waved them off with a smile, knowing they’d find her when they were ready to leave. To her surprise, the dark-eyed man located her and claimed a dance or two. He vanished when she forgot she was dancing with him, and turned away.

An arm encircled her waist, sliding possessively across the silk of her camisole. Margrit returned to her body with a jolt that shot electricity through her fingers and toes. It made a cold knot in her belly that melted to warmth, spilling down to pulse between her thighs, making her laugh with desire. She closed her eyes and wound a hand up and backward, to wrap her fingers around the nape of her partner’s neck. His hands slid to her hips, rucking up the hem of her top, to settle against her suede skirt. He could be anyone. He could be the killer; he could be the dark-eyed man who’d asked her to dance earlier. Not knowing was half the fun.

Irrational, she whispered to the beat of the music, and let herself go again.

He was a strong dancer, very sure of himself, his hands intimate without being obtrusive. The two of them fit together well, despite his height, and Margrit tucked her hips back with a purring smile. She felt the curve of his body as he lowered his head, felt the warmth of his breath against her shoulder, making her shiver. He moved a palm to her waist, then pulled her closer, protectively, as if he could warm her with his own body heat.

Margrit relaxed back into him, grinning lazily, eyes still closed. His breath spilled over her shoulder again, against her neck, and she tilted her chin up, exposing more throat. He hesitated, close enough that she could feel the heat of his mouth against her skin before he murmured, “I didn’t kill that girl.”

Adrenaline crashed through Margrit, leaving her fingertips cold and a twist of sickness under her sternum. She straightened abruptly, the sensation of flight and freedom lost. As if in response, the strobe lighting cut out. Spotlights swept the crowd instead, dancers standing out in brilliant purples and oranges. Sweat and alcohol and perfumes mingled in the air, giving it a too-sweet scent, like over-sugared candy. Margrit could hear individual voices, as if the cacophony of music had suddenly died, leaving everyone shouting into silence. She clenched down on the panic in her belly, feeling heavy when an instant ago she’d been soaring weightless among the stars.

“I didn’t kill her.” Beyond the urgency in his voice, Margrit detected a hint of an Eastern European accent that hadn’t been noticeable the night before. She latched onto the detail; it would be something to report to Tony.

A deep breath calmed the fear boiling in her stomach and left behind nervous excitement. If Tony was watching the screens, she might be able to delay the blond man until he arrived. It was a risk worth taking.
