As Mr. X crossed the parking lot and headed for the Caldwell Martial Arts Academy, he caught a whiff of the Dunkin' Donuts across the street. That smell, that gorgeous, thick smell of flour and sugar and hot oil, was heavy in the morning air. He looked over his shoulder, watching as a man emerged with two white-and-pink boxes under his arm and a huge travel mug of coffee in his other hand.

That would be a nice way to start the morning, Mr. X thought.

Mr. X stepped up onto the sidewalk that ran beneath the academy's red-and-gold awning. He paused, reaching down and picking up a stray plastic cup. Its previous owner had been careful to keep an inch of soda in the bottom so his or her cigarette butts could enjoy floating around while they waited for someone else to throw them away. He pitched the nasty swill in the trash and unlocked the doors to the academy.

The Lessening Society had turned a corner in the war last night, and he was the one who had done the deed. Darius had been a powerhouse of a vampire, a member of the Black Dagger Brotherhood. One hell of a trophy.

It was a damn shame there was nothing left of the corpse to mount on a wall, but Mr. X's bomb had performed adequately and then some. He'd been at home, listening to his police scanner, when the report had come in. The op was everything he had planned it to be, perfectly executed, perfectly anonymous.

Perfectly deadly.

He tried to recall the last time a member of the brotherhood had been taken out. Well before he'd joined the society decades ago, certainly. And he'd expected to get a few pats on the back, not that such accolades motivated him. He'd figured he might even get a bonus out of it, maybe an expansion of his sphere of influence, maybe a greater geographic radius in which to work.

But the reward… the reward was more than he'd expected.

The Omega had paid him a visit an hour before dawn. And conferred upon him all the rights and privileges of Fore-lesser.

Leader of the Lessening Society.

It was an awesome responsibility. And exactly what Mr. X had been angling for.

Power granted was the only form of praise he was interested in.

Walking with long strides, he headed for his office. The first classes would start at nine, and there was plenty of time for him to lay down some of the new rules for his subordinates in the society.

His first instinct after the Omega had left was to send an announcement out, but that would have been unwise. A leader gathered his thoughts before he spoke; he did not rush to the podium to be adored. Ego, after all, was the root of evil.

So instead of crowing like a fool, he'd gone outside and sat down in a lawn chair, looking over the meadow behind his house. In the dawn's nascent glow, he'd reviewed the strengths and weaknesses of his organization and allowed his instincts to show him the way to manage both. From the tangle of images and thoughts, patterns had emerged, the future becoming clear.

Sitting behind his desk now, he signed on to the society's secured Web site and made it clear that a change in leadership had occurred. He ordered all lessers to come to the academy at four P.M. that afternoon, knowing that some would have to travel, but none was farther away than an eight-hour car ride. Anyone who did not show up would be excised from the society and hunted down like a dog.

Gathering the lessers together in one place was rare. At this time their numbers hovered in the fifty to sixty range, depending on the number of kills the brotherhood got in on any given night and the number of new recruits that were brought into service. The society's members were all in and around New England. This concentration in the northeastern United States was dictated by the prevalence of vampires in the area. If that population moved, so would the society.

As had been the way throughout the generations of the war.

Mr. X was aware that getting the lessers to Caldwell for an audience was critical. Although he knew most of them, and some of them rather well, he needed for them to see him and hear him and measure him. Especially as he redirected their focus.

Calling the meeting in the daylight was also important, as it would ensure they weren't ambushed by the brotherhood. And he could easily pass it off to the academy's human employees as a seminar on martial-arts technique. They would hold the gathering in the large conference room in the basement and lock the doors so they wouldn't be intruded upon.

Before he signed off, he posted an account of his elimination of Darius, because he wanted the slayers to have it in writing. He detailed the kind of bomb he'd used, the way to manufacture one from scratch, and the method for hardwiring the detonator into a car's ignition system. It was so easy once the thing was set. All you needed to do was arm it, and then the next time the engine was started, anyone in the car was turned to ash.

For that split second of payoff, he'd tracked the warrior Darius for a year, watching him, learning the rhythms of his life. And then two days ago, Mr. X had broken into the Greene Brothers BMW dealership when the vampire had sent his 6-series in for service. The bomb had been set, and then last night Mr. X had walked by the car and activated the detonator with a radio transmitter without missing a step.

The long, concentrated effort to set up the elimination was not something he shared. He wanted his lessers to believe he was able to execute such a flawless move on a whim. Image and perception played important roles in the creation of a power base, and he wanted to start building his command credibility right away.

After signing off, he leaned back in his chair, steepling his fingers. Ever since he'd joined the society, the focus had been on reducing the vampire population through civilian eliminations. This would remain his overall goal, of course, but his first decree would be a change in strategy. The key to winning the war was taking out the brotherhood. Without those six warriors, the civilians would be naked against the lessers, undefended.

The tactic was not a new one. It had been attempted in generations past and discarded numerous times when the brothers had proven either too aggressive or too elusive to be taken out. But with Darius's death, the society had momentum.

And they had to do something differently. As it stood now, the brotherhood was cutting down hundreds of lessers every year, requiring the ranks to be fed with new, inexperienced slayers. Recruits were trouble. They were hard to find, hard to induct into the society, and not as effective as seasoned members of the society.

This constant need to bring in new men led to a critical weakness for the society. Training centers like the Caldwell Martial Arts Academy served an important purpose in identifying and enlisting humans to join the ranks, but they were also points of exposure. Avoiding interference by the human police-and protecting against a siege by the brotherhood-required constant vigilance and frequent relocation. The moving around from place to place was disruptive, but how else could the society stay stocked and yet the centers of operation not be ambushed?

Mr. X shook his head. At some point he was going to need a second in command, though he wouldn't bring one on for a while.

Fortunately, nothing he was going to do was particularly complex. It was all basic military strategy. Marshal your forces. Coordinate them. Acquire information on the enemy. Advance in a logical, disciplined manner.
