"That amount of power in an untrained practitioner just didn't seem natural," Boo said. "I've been thinkin' about it myself. We woulda detected it if that girl was buildin' it all up inside herself. You get some spillover even in experienced people. It's almost as if she was channelin' it from somewhere. I'm more curious about that. Where's it comin' from?"

"We won't know until we catch up with her," Liz said, grimly. "So far, she's managed to blend in far too well. She could stay hidden until it is too late."

"Not really," Boo said, encouragingly. "This is the Vieux Carré. It's a community. We're aware of strangers. Someone will know where she went."

In reference to strangers, Liz had taken note of a couple of large, muscular men walking behind them on the other side of the street. Wearing the usual working uniform of button-down shirts and twill pants, they could have been a couple of bouncers on their way to work, or a pair of musicians going anywhere, but she noticed that they kept pace with her and Beauray, although taking care to remain at least a dozen yards behind them. They turned when she turned, crossing the nearly deserted street in the middle of the block to follow them along a narrow street that ran parallel to Rampart. Once they crossed Canal into a rundown street that led between a huge yellow brick building with boarded up windows and an empty lot, it became an undeniable fact that the two men were following them with a purpose in mind. A glance at her companion told her that he had noticed them, too. His hands, deep in the pockets of his ratty coat, were working.

Liz paused very casually to dig into her handbag, coming up with a handkerchief under which she concealed one of her government-issue containers. As though she was freshening up her lipstick, she unscrewed the small vial and dribbled a little of the powder into her palm. The men had no choice but to saunter slower, and pretend to study the elderly brick building. As they came within a few yards, Liz put her handkerchief to her nose and blew a few grains of the dust toward them. The grains, part of a sensing cantrip she had learned in her first year at the department, revealed no magic in particular about their pursuers. Ordinary common-or-garden thugs. Well, she'd heard there was street crime in New Orleans. She should be prepared. And she was not alone. That was good. She started walking again, faster. The two men behind them picked up the pace, too.

As they neared the center of the lonely street, she readied the chamomile-and-gunpowder mixture that would stun or knock out an attacker.

What she couldn't have foreseen was that there were four of them. The other two heavies were waiting at the head of the narrow street where it came to a dead end. As Liz and Boo-Boo came within a few paces of the cross street ahead, they stepped out from the brick doorway where they had been concealed.

The surprise nearly spoiled her aim, but Liz reminded herself the British Secret Service was made of tougher stuff than street muggers. With amazing clarity of mind that surprised even her, she turned and lobbed the sandy mixture at the large man farther to the right. A flash of light erupted from Boo-Boo's hands, hitting the left-hand pursuer square in the chest. Both ruffians went flying several feet.

"Have you got any more of those?" Liz asked. He grabbed her arm and started to hustle her back the way they had come.

"'Fraid not, Liz," Boo said.

"Pity." They started running.

The second pair, seeing their quarry escaping, put on a burst of speed and ran after them. The first two had not been knocked completely unconscious. Liz dodged around the first one, who lay partly across the cracked sidewalk. He made a grab for her ankles. In evading his grasp, she nearly tripped over the second thug, who was on his hands and knees, shaking his head like a stunned steer. He wrapped an arm around her leg and hung on. Liz let out a squawk. Time to see if those unarmed combat lessons she had paid for had done her any good.

Boo-Boo, who had made it nearly all the way back to Canal, turned at the strangled sound. Liz was now surrounded by all four of the ruffians. One of them had snatched her purse and held it away from her, while two of the others grabbed her arms. The third one hovered over her menacingly, drawing back a fist. Boo-Boo ran back to help her, but arrived just half a second too late. In the blink of an eye, Liz squirmed loose from one man, kneed another soundly in the crotch, and was chanting with intent as her free hand worked in a hazy pattern Boo-Boo recognized as a confusion spell. She was pretty good, now that he had to admit it. The trouble was that her attention was divided between more than one person. Even if she succeeded in clouding the mind of one man, the other two would still be threats.

He circled the tableau, wondering where to jump in. Liz'd done an admirable job of getting herself out of a jam, but she wasn't free yet. The three men feinted toward her, trying to catch her off balance by drawing her attention. She hadn't much time before she had to cast her spell or let it fade. The fourth man had gotten over the radiating pain and was climbing up from the ground, angrier than ever. Though he would have been curious to see how his efficient British counterpart would handle the situation, it was time to intervene.

Boo pulled a bag of dust out of his pocket. With only a cursory glance to make sure it was the right one, he slammed it down on the ground in the midst of the group. Billows of noxious green rose around the group. They wailed miserably, clawing at their faces and one another. Boo-Boo felt a twinge of guilt. He hated to use that stuff because of what it did to people—the residual effect gave them nightmares for days, sometimes as much as years after exposure—but it was really effective. It was comprised largely of graveyard dust and bile, but it had half a hundred other ingredients. One man cried out in alarm and struck out with a fist, smacking his nearest comrade in the ear. The man he struck responded with a wild yell and began flailing with both arms, dropping Liz's purse. Things were getting just a little too dangerous in there.

Pulling the lapel of his ragged jacket over his mouth and nose, Boo-Boo reached into the roiling green smoke and pulled Liz free. He helped her over to lean against the wall of the derelict department store while she coughed the powder out of her lungs.

Chanting the counterspell in a whisper so it would only affect her, he kept an eye on the four men while she recovered her sanity.

"What was that?" Liz demanded, coughing.

"Fear dust," Boo-Boo said. "Local product. Effective, isn't it?"

"Very." Liz watched the men screaming and struggling, fighting against invisible opponents and hitting the others in their frenzy. "Will they recover?"

"Sooner or later," Boo-Boo said. "They're fightin' with their inner demons just now. I'll give 'em a moment before I stop the effect and ask 'em questions. It's amazin' how cooperative they get when the terror stops. They see nightmares, monsters, all kinds of terrible things. I hate to use it, but it works."

"You're right," Liz said, shuddering. "It does."

"What did you see?"

"Mr. Ringwall."

Boo-Boo grinned. "Hey, now, hold on. I know those two." He pointed at the two men who had been waiting concealed at the head of the street, a white man with a handlebar mustache and a shaved head, and a black man with a grizzled beard clipped to a point. "One of them works as a bouncer for one of the jazz clubs on Bourbon. The other is security in the state museum buildings. They're not the kind who normally go in for muggin'."

Over Liz's protests, Boo-Boo pulled them out of the miasma and counterspelled them. The first pair, startled at the sudden movement, cowered, throwing up their hands. The eyes of the other two stopped whirling. The men shook themselves like large dogs coming out of a lake. The bearded man's mouth dropped open.
