“It’s so much easier when we take the Tuatha Express,” I mumbled.

“The cost of travel should be high,” said Tybalt. He straightened and paced toward the entrance to the antechamber. “It’s what keeps us from roving frivolously.”

“Etienne seems to think it’s pretty hard, at least when he’s going more than a few miles,” I said. “He doesn’t usually teleport casually. But Chelsea isn’t playing by the usual rules.”

“Yes. I know.” Tybalt shook his head. “The shadows are starting to push back against us. They only do that when their destination is unclear, or when they have nowhere to end. The tethers between the Shadow Roads and the Summerlands are beginning to fray—as are the tethers between the Shadow Roads and the mortal world. If this continues too long, we may find ourselves with nowhere to run.”

I thought about that for a second, then put the thought aside. It was too big a problem for me to fix; it was something I couldn’t hit. All I could do was get Chelsea to stop ripping holes and let the people who could fix things get to work.

Of course, that meant we couldn’t stay huddled in this tiny antechamber forever. “Riordan’s guards are mostly Folletti,” I said. “I can tell when they’re nearby, but only if I’m looking for them. Most of the time, they’re going to be effectively invisible.”

“Charming,” said Tybalt.

“Yeah. Can you scout the hall? Just make sure we’re alone before we leave here.”

“It would be my pleasure,” said Tybalt. The smell of musk and pennyroyal swirled around him and he was gone, replaced by a large tabby tomcat. He walked over to me, rubbed himself against my ankles, and turned to slink out of the antechamber, vanishing behind the tapestry that covered the entrance.

Quentin had his breathing back under control. He came to stand next to me, and we stayed where we were, waiting for whatever was going to come next. I kept one hand on my knife and the other on Quentin’s shoulder, ready to shove him behind me if something attacked us. I could take the damage. He couldn’t.

The minutes ticked by. I was on the verge of becoming genuinely worried when the fabric of the tapestry stirred, and Tybalt slunk back into the room, ears pressed flat and tail carried low to the ground.

I let out a relieved breath. “Took you long enough,” I said.

The smell of pennyroyal and musk rose around him. He straightened on two legs, a troubled expression on his face. “Going unseen is an art as much as a skill,” he said. “I can smell the Folletti when I go in feline form. That doesn’t make it wise for me to risk discovery by exposing myself where they might see.”

“What did you find?”

“These chambers are scattered all along this hall, and the ones to either side. It seems our Duchess Riordan is quite fond of the spy’s art, providing she can control the placement of the spies. I doubt she would be pleased to know we were using her clever hidey-holes against her.”

“If you don’t want people using your secret little rooms for nefarious purposes, you shouldn’t make them this easy to find,” I said. Then I paused. “Or maybe they’re not just here for spying on guests. Quentin, remember when you showed me how to navigate the servants’ passages at Shadowed Hills?”

Quentin blinked as understanding dawned. “Give me a second,” he said, and moved to the back of the antechamber.

Tybalt watched him go before turning his frown on me, clearly puzzled. “Would you care to explain?”

“Most knowes—ones that don’t belong to the Court of Cats—are built to suit the nobles who own them. Even the good nobles want their servants to be invisible, although most don’t take it as literally as Riordan here. Service is supposed to be quiet, efficient, and only noticed when something goes wrong. So they hide little passages and back routes through the knowes, to make it possible for their servants to stay out of sight.”

“Ah.” Tybalt frowned. “The Divided Courts are sometimes more alien to me than I like to admit.”

“If it helps at all, I think they tend to feel the same way about the Court of Cats.”

Tybalt shook his head, still frowning. “I am not sure it helps anything to know that we are all strangers to one another.”

“Got it!” Quentin’s triumphant whisper stopped me before I could say anything I’d regret later. I turned to see him standing in front of a narrow open rectangle in what had seemed to be a solid wall only moments before. He was grinning, visibly pleased with himself—as well he should be. “She uses a pressure code to keep the doors closed. It’s pretty clever, but it’s also pretty common. I’ve seen it in a bunch of knowes.”

“My little cat burglar,” I said dryly. “How proud your parents must be.”

His grin, if anything, brightened. “I’d bet you a dollar that you’re right.”

“As long as it’s not a Canadian dollar, you’re on.” I started toward the opening. “Let’s see what’s behind door number one.”

“Is the answer ever ‘unending pain and a suffering beyond imagination’?” asked Tybalt. He still followed me. Either his sense of self-preservation was weakening, or he was confident that whatever might be lurking up ahead would eat the rest of us first.

“Sometimes,” said Quentin. “Other times, it’s a pantry.”

I smothered my laughter behind my hand as I stepped through the door Quentin had managed to open in the wall, gesturing for the others to wait. They did, Quentin calmly, and Tybalt with obvious annoyance. At least he was listening to me. That was going to be essential if we were going to get out of this with everyone still breathing.

The floor on the other side of the wall was as plain as the antechamber behind me. I still stepped carefully, testing the wood with my toes before moving forward. If there were any booby-traps, they were the kind that needed more than a little weight to trigger them.

The servant’s hall was dark, lacking the glowing spheres that dotted the hallway outside. I paused, then dug the Luidaeg’s Chelsea-chaser out of my pocket. Its glow brightened as I brought it into the open, chasing back the worst of the shadows. It was in its neutral state, glowing like a handful of captive starlight…but it hadn’t been this bright since it was first activated. I wasn’t sure what that meant. I had to hope it was a sign that Chelsea had been here at least once, and might be here again.
