"We'll call a cab," Roger said. "Once it's standing here with the engine running, you'll go over to the tree and see if you can get her to come out. If she's there, and if she answers, we can hopefully all be on the FDR before anyone can stop us."

He looked out the window again. "If so, then you two can hole up in a hotel somewhere while I go talk to this Velovsky character and see how much of this mess he can clear up."

Caroline sighed. "I just wish there was more we could do."

"Me, too," Roger said. "But I don't know what else to suggest."

"I know," Caroline said reluctantly. "Could we at least...? No, never mind."

"What?" he asked. "Come on, tell me."

"Could we at least use the hide-a-bed here instead of one of the bedrooms?" she asked hesitantly. "I know she was watching when I did the code downstairs. That way, if she gets into the building but can't remember the apartment code, we'd hear her knocking."

"Sure," Roger said, suppressing a grimace. He never slept well on hide-a-beds, and Caroline knew it.

But aside from that, it was a good idea. "Go get our stuff and I'll get the bed set up."

"Okay." To his mild surprise, she leaned over and gave him a quick kiss. "Thank you."

"No problem," he assured her.

And besides, he thought as he stacked the couch cushions against the wall, no matter where they settled down for the night, he wasn't going to sleep well.

The sun was just coming up over Queens, and Fierenzo and Powell had been sitting in the stakeout car for half an hour, when the Whittiers finally made their move. "There they are," Fierenzo announced, nudging his partner as he peered back over his shoulder.

"Where?" Powell asked, turning around.

"Cab," Fierenzo said succinctly, pointing to the vehicle that had pulled up in front of the apartment building behind them. A moment later the Whittiers appeared, the husband going straight to the cab's back door and opening it. To Fierenzo's mild surprise, though, the wife headed instead across the street.

"Where the hell is she going?" Powell muttered.

"Looks like she's revisiting the crime scene," Fierenzo said, frowning as she stepped over the low fence and waded her way through the bushes to the tree with the broken-off limb. Crouching over, she leaned her face right up to the bark. "Looking for something, maybe?" he added.

"If she is, she's talking to herself while she's doing it," Powell told him.

"You're right," Fierenzo agreed, frowning harder as he watched the woman's lips. Movement, then a pause; then movement, then another pause. As if she was saying something and then waiting for an answer.

An answer that apparently wasn't coming. Thirty seconds later she gave up and turned back toward her husband and the cab. "Here they come," he said, swiveling back to face forward and turning the key. The engine sputtered for a moment and then caught, blowing cold air through the vents at them.

In the mirror he watched as the Whittiers climbed into the cab and the driver pulled away from the curb. It passed Fierenzo and Powell and headed for the next street, its left turn signal flashing. "Here we go," Fierenzo muttered, pulling out onto the street as the cab slowed for the turn. "Five bucks says they're going for the FDR—"

"Hold it," Powell interrupted, pointing to their right. Beyond the tall fence that encircled the park, a dark-haired man was running toward them, waving both arms frantically. "What's he doing in there with the gate still locked?" Powell muttered.

"See what he wants," Fierenzo said, glancing toward the cab as it disappeared around the corner.

"Maybe we can call it in and keep going."

Powell cranked down the window, letting in a fresh flood of cold air. "What's the matter?" he called.

The man skidded to a halt, opened his mouth, and screamed.

Fierenzo jerked as the sound hammered through his head, the car leaping beneath him like a bucking horse. The wheel twisted in his hands, the street and park and whole damn city tilting sideways as up and down suddenly lost their meaning. Dimly over the sound he heard Powell yelling something—

And then the world straightened out; and with a rush of adrenaline he saw he was headed straight for the curb.

He twisted the wheel, but it was too late. With a spine-jolting bounce the car careened up over the curb and rolled itself up against a lamppost.

"You okay?" Fierenzo asked, shaking his head to clear it.

"Yeah," Powell grunted, sounding as dazed as Fierenzo felt. "Hell—there he goes."

The man had reversed direction and was running back across the park toward the fence at the far side. "Oh, no, he doesn't," Fierenzo growled, popping his seat belt and shoving open his door.

Scrambling awkwardly out against the upward tilt, he hit the ground and charged across the street.

He'd heard echoes of that same scream last night, and he had no intention of letting this one get away.

He was across the street and making for the gate when his quarry spun around in mid-run and let loose with another scream.

He was at least twice as far away from Fierenzo as he'd been the first time, but the extra distance didn't seem to make a bit of difference. Once again the ground tilted violently; and this time, with no car wrapped protectively around him, he fell face first toward the iron fence. More by luck than anything else, he managed to grab one of the bars, halting his forward momentum and giving him something to hang onto as the world took itself on another spin. A moment later, without any memory of having fallen the rest of the way, he found himself lying on the ground. Blinking away the last few sparkling stars, he lifted his head and looked around.

The man had disappeared.

There was the sound of hurrying footsteps, and he swiveled around on his hip as Powell dropped to a crouch beside him, gun in hand as he stared through the fence into the park. "Where'd he go?" he demanded.

"What are you asking me for?" Fierenzo grunted, using the fence for balance as he pulled himself back to his feet. "Weren't you watching?"

"Of course I was," Powell said disgustedly, giving Fierenzo an assist with his free hand. "Right to the point where he ran behind one of the trees, and that was the last I saw of him. You okay?"

"I think so," Fierenzo said, rubbing his palms against his pant legs to dry them as he peered through the fence. The man had vanished, all right, just like Melantha and the old woman from last night.

This was starting to get very annoying. "That song of his sound familiar?"

"Like the one we heard last night," Powell confirmed. "Reminds me of those nonlethal sonic weapons the military's been playing around with."

"Only this guy was doing it without assistance," Fierenzo said.

"Unless he had something hidden under his coat."

"Maybe," Fierenzo said, looking down the street. "Regardless, he's given the Whittiers a nice little head start on the day."

"So they've been lying the whole time," Powell said sourly. "Damn. I'd been hoping they really were just innocent bystanders."

"Don't give up on them just yet," Fierenzo cautioned. "People smart enough to successfully lie to experienced cops like us should also be smart enough not to make their getaway in a cab with big numbers plastered all over it."

"Good point," Powell said, frowning. "It's almost like they didn't even know we were here."

Fierenzo nodded. "Which suggests our friend with the noisemaker may have been running interference without their knowledge."

"Cyril?"

"Or Aleksander, or Sylvia, or someone whose name we haven't heard yet," Fierenzo said. "Take your pick."

Powell grimaced. "Who the hell are these people, anyway?"
