I don’t know which was creepier, the dog’s presence or Shay’s calmness. “Shay, nothing is what it was. The Dead are trapped here, so maybe the dog is, too. Maybe it reacted to the fact that you brought it home. Dogs respond to kindness, right? It’s still a dog.”

“His name is Uno,” he said.

“What?”

Shay gave me a wry smile. “I thought it was a joke at the time. He had only one head, so I named him Uno.”

“The three heads are from Greek myth, not Faerie,” I said.

Shay sat in an armchair. “That’s the joke, isn’t it? I came up with the name based on something that didn’t exist. Only, the joke’s on me. It’s a hellhound, and I’m going to die.”

“Stop saying that,” I said.

Shay shrugged. “That’s the only way it goes away that I’ve ever heard.” He pursed his lips. “Actually, it sort of gets rid of you.”

“This isn’t my area of expertise. Let me look into it,” I said.

Shay stared into his tea mug. “Funny thing—I dreamed of Robyn the night the dog appeared. Robyn would have tried to do something about it showing up, but there was nothing he could have done. He couldn’t stop his own death.”

I poked him against his leg with my boot. “Will you stop? Robyn died trying to do a good thing. He loved you. I thought he was kind of a jerk, but he loved you.”

Shay leaned his head back and laughed. “The two of you had something in common. He thought you were a jerk, too.”

He looked back at the dog. “I just thought of something, Connor. If Uno came for me, maybe I’ll get to see Robyn again. I never had much faith in Christianity. Maybe TirNaNog is where I’ll end up.”

I didn’t have the heart to tell him that the reason the Dead were roaming the Weird was because TirNaNog might not exist anymore. “Yeah, maybe, but as far as I’m concerned, I didn’t save your ass last midsummer for you to end up dog food.”

Shay chuckled. “Now you have something else in common with Robyn: promising to protect me when you know you can’t.”

“I’m not listening to any more of this. I’m going to find out how to get rid of this guy,” I said.

Shay shifted closer to me. “I don’t think I can ask for more than that, but don’t feel bad if you can’t. It’s not your fault.”

“I’ll find something, Shay,” I said.

He took the cold tea from my hand and walked me to the door. “Thanks, Connor. Maybe some revelation is at hand for me, no? Maybe it means something important. I bet not every human gets to have a hellhound in their living room, even in the Weird.”

“Be careful, Shay. I’ll get back to you.”

Shay amazed me. I didn’t think I could do anything for him. I had never encountered a hound from TirNaNog, but all the old tales ended the way Shay said they did. Whoever the hound came for, died. If he was doomed, the least I could do was try to help. I wasn’t really big on abandoning people to fate. My life would be a lot easier if I were.

The early-morning cold remained, the sky a stark white with the threat of snow. When I’d arrived home the previous night, I spent the evening outlining research ideas for Shay’s dog problem. Which, of course, led all too easily to late-night Internet surfing on topics that had nothing to do with hellhounds. Which, more of course, I should have known would lead to an early-morning phone call from Murdock asking me to meet him since I had barely gotten any sleep. He told me to wear clothes and boots I didn’t care about, so I wore the oldest pair of jeans I owned and an extra layer of sweatshirt.

I walked the three blocks to the location Murdock gave me. Trucks barreled down Fargo Street, whipping sand into the air. Near the corner of Cypher Street, large blue utility vans emblazoned with MASSACHUSETTS WATER RESOURCES AUTHORITY on the side blocked part of the intersection. MWRA workers placed cones and portable metal barricades around an open manhole. Wearing jeans and an old Red Sox jacket, Murdock stared into the hole in the street. I assumed he had borrowed the jacket from one of his brothers because I could not imagine Murdock keeping a stained piece of clothing. His new casual attire was amusing me.

A sewer worker banged on something in the hole below us. “Please tell me you asked me to dress like this because we’re going hiking,” I said.

He chuckled silently. “No such luck. The MWRA gave us an idea of where the body at the headworks might have gone into the system based on the time on the broken watch. Turns out the tunnel he came out of has only two feeder pipes. This is where they meet.”

I slouched. “We’re going in the sewer.”

“Yep. It’s a possible crime scene.”

The worker banged some more. “What’s he doing?” I asked.

“Scaring away the rats.”

“Great.”

Joe burst into the air in front of the detail officer directing traffic. The guy ducked like a giant insect was attacking him. “Am I too late? Did I miss anything?” Joe asked.

Murdock watched him flutter around the manhole. “Just in time, Joe.”

Joe showing up at two different crime scenes was a little too coincidental. “How the hell did you reach him? I can’t get him to show up anywhere on time.”

Murdock withdrew a small clear bottle from his pocket. Motes of yellow light danced inside. “He gave me a bunch of these.”

Glow bees. They were concentrations of essence that absorb voice sounds. Messages became imprinted on the essence, which homed in on the recipient when released. They worked best with strong body signatures—like the fey had—and since Murdock’s signature was hyped enough to create a body shield, a glow bee would be easy for him to use. Humans loved to play with them although cell phones worked a lot faster. The sewer worker climbed out. Murdock gestured. “After you.”

I shook my head. “I believe it’s your case, Detective. I’m a consultant here.”

Murdock placed one foot on the ladder. Joe zipped in ahead of him. The worker handed me a flashlight, and I followed them down. A cast-iron pipe ran through a low, square tunnel. The pipe took up most of the space, and we crouched against a brick wall. A dull odor filled the air, not overwhelming, the tang of chemicals and dankness. “It doesn’t smell as bad as I thought,” I said.

Murdock swung his own flashlight toward the end of the tunnel. “That’s because this part’s sealed. The catch basin is up that way.”

“Excuse me while I get ahead!” Joe said. His squeal of laughter trailed down the tunnel as the pink glow of his wings dwindled into the distance.

Murdock shimmied sideways along the pipe. I flicked the beam of my light at his feet, then behind me. I’m not a fan of rats sneaking up on me. “Don’t you guys have crime-scene people to do this?”

Murdock cleared his throat. “Short-staffed. They said they don’t look for crime scenes, they investigate them. Besides, they can’t do what you do.”

True. When I climbed down the ladder, my sensing ability got immediate hits, mostly dwarves, several anomalous ones that meant solitaries, and the distinctive signature of the Dead. The Dead felt different than the living. Their signatures had a dulled aspect to them that distinguished them from living ones. “Too many to sort in this area.”

Murdock pushed forward. “I don’t even want to think about so many people down here.”

The body signatures faded the farther we moved from the manhole. Homeless squats appeared under the pipes, faint shimmers of essence indicating they had been used a while ago. The distant sound of water reached my ears at the same time as the stench that I expected to find in a sewer. Joe’s pink essence appeared and reappeared, closer now. He was either popping in and out of sight or passing in front of an opening.

“I’m down to five body signatures, Murdock. Two dwarves, a Dead fairy, a solitary I don’t recognize and, I’m not sure, but I think it might be a Dead human.”
