"Oh?" Agnes looked into the sky. "So it will. Thank you."

The Nix gave Agnes the strength to cut the vagrant's torso in two.

"Are you taking this one back to Kingsbury Run?"

Agnes nodded and kept cutting.

"May I make a suggestion?"

Another abrupt nod as Agnes began to saw off the legs.

"Throw the pieces in the creek. Someone's bound to see one of them floating along. But hide the head."

She paused. "And maybe the hands. Yes, hide the head and the hands. They'll need to call in help to dredge the creek, and that's bound to draw attention."

Agnes rocked back on her heels and stared out into the night, then nodded. "Yes, I think I shall. Thank you."

"I'm here to help."

The Mad Butcher of Kingsbury Run. Agnes hated the name the press had given her. The Nix agreed it was rather harsh. Mad? Yes. But "butcher" was uncalled for. Agnes was a qualified surgeon, and the expert dissection should have made that clear.

Several people had speculated that the killer was indeed a surgeon, maybe even a crusader, but the public preferred the image of a raging maniac with a meat cleaver and bloodstained apron. If that scared them more, well, the Nix wasn't about to argue.

Some had even whispered that the killer could be a woman, because the first two victims had been emasculated, but this idea was quickly shot down. No woman would ever do such a thing—to suggest it was to taint the very notion of womanhood. That had made the Nix laugh so hard she'd nearly popped right out of Agnes's body. Clearly these people didn't run in the same circles she did.

As they moved through Agnes's clinic, the Nix basked in the fear that swirled about, thick as the foundry smoke down by the river. In the corner, two vagrants whispered about a shadow they'd seen in Hobotown, a monstrous shadow that had twisted up from the very earth itself, butcher's knife in hand.

Two younger men in hobnailed boots swapped "secret" details of the mutilations, each trying to outdo the other. A young mother gathered her two children closer and tried to stop up their ears, her eyes dark with fear.

Agnes was oblivious to the chaos she was causing, intent only on her day's appointments. Cure them by day; kill them by night. The fact that Agnes failed to see the irony—the perversity—of this only made it all the more delicious to the Nix. Of course, it would have been better if Agnes could share the irony with her, instead of trudging through the killings with all the joy of a factory worker putting in a twelve-hour shift. The Nix had held out every hope of converting Agnes, of introducing her to the joys of death and grief and chaos, but she knew now it would never happen, and if she kept pushing, this would be the first time she was evicted by her living partner. She wasn't ready for that—there was still much feasting to come. So she kept silent.

Agnes was in search of victim number thirteen… or so the Nix hoped. They'd finally found the decapitated man and woman Agnes had left in the East Ninth Street dump. At last, the city was in a true panic. To the Nix, there was no question what Agnes should do now. Strike again, while they were still reeling from the last killings. Make this one the worst yet, the most horrific, and she would not only have their attention, she'd own it.

Agnes didn't see it that way. Now that the city had noticed, she wanted to sit back and see whether they understood her message. For two days, they'd been arguing about this. Finally, the Nix had convinced Agnes to take this walk.

As they headed off the street, the Nix saw a shape flicker through the shadows.

"Over there," she said. "To your left. What's that?"

Agnes's gaze swept left so quickly the Nix saw only the flicker of a shadow. Frustration washed through her. For two days she'd been telling Agnes they were being followed. The hunter kept to the shadows, but the Nix had noticed that he failed to cast a shadow himself, which could only mean one thing—their stalker was a spirit. Probably an angel. One had followed her before, and she'd dispatched her easily enough, but the Nix wasn't fool enough to ignore the threat another would pose.

An angel had taken her to that supernatural hell dimension, where she'd spent two centuries, and could do so again with another swipe of those damnable swords. As a demi-demon she'd been impervious to the Sword of Judgment, but she'd lost that immunity when she'd taken over a human form.

But Agnes had shrugged her off with a nonchalance that still sent waves of fury through the Nix. So long as the stalker wasn't coming for her, Agnes didn't care. This only confirmed the Nix's suspicion that she'd outlasted her usefulness to Agnes.

Agnes picked her way down a trash-strewn hill, then paused and inhaled.

"Smoke," the Nix murmured. "Something's burning over by Hobotown."

Agnes hurried forward, stumbling over piles of tin cans and scraps of lumber. When they rounded the next building, the sky turned orange. Distant flames lit the night sky.

"No," Agnes whispered. "No."

She rushed forward. Hobotown was afire, ringed by fire trucks. The firemen were just standing there, leaning on shovels, sitting on upturned buckets, watching the shantytown burn.

The Nix strained to hear the shrieks of dying men. For agony, there was nothing like burning alive. Yet all she heard were the shouts of the police and firemen, laughing and calling to one another as they enjoyed the spectacle. Finally she picked up the sweet sound of sobbing, and traced it to a line of police paddy wagons. Men were being loaded into the trucks.

A young man in an overcoat strode out from the line of paddy wagons. Eliot Ness. The Nix recognized him from the articles Agnes pored over.

"Burn them to the ground!" he shouted. "Leave them no place to return to. That will solve the problem."

"No," Agnes whispered.

She swayed on her feet. The Nix felt a sharp pain.

Agnes clutched her chest, gasping, and sank to the ground.

"No!" the Nix said. "Get up!"

Agnes lay on her back, mouth opening and closing, eyes wide and unseeing. The Nix let out a howl of frustration as she felt Agnes's life slipping away. Involuntarily, the Nix's spirit began to separate from Agnes's body. She tried to throw herself free but couldn't. As Agnes died, the Nix was trapped there, tethered to Agnes's earthly form. As she struggled, a figure stepped through the building beside them. A dark-haired, handsome man.
