“We should get back to camp,” Birchfall warned. “WindClan are still on our land.” Eyes round with worry, he glanced at his Clanmates before bounding away. Lionpaw raced after him, Cloudtail and Dustpelt on his heels. The forest floor blurred beneath his paws as they sped for home.

“Firestar!” Dustpelt exploded through the thorn tunnel and called to the ThunderClan leader.

Lionpaw saw with relief that the camp was the same as when they had left. Foxpaw and Icepaw were passing up brambles to Brightheart, who stretched up to weave them into the thorn barrier. Spiderleg was dragging more branches out from behind the medicine den, while Berrynose and Honeyfern pressed mud and leaves around the bottom of the barrier to root it more firmly into place. Graystripe paced outside the nursery, the fur bristling along his spine. Mousefur and Longtail crouched on Highledge.

Firestar looked up sharply. “Have they left?” He had been talking with Brambleclaw in the middle of the moonlit clearing.

Dustpelt shook his head.

“What?” Firestar dug his claws into the soft earth.

“They’ve split up into three groups and disappeared.”

Graystripe hurried from the nursery. “Split up?”

“They must be trying to weaken us by dividing us up,” Brambleclaw growled.

“The attack on the camp was just to get our attention,” Firestar concluded. “They want to draw us out into the forest.”

“If they’ve split up, they’ve weakened themselves too,” Dustpelt pointed out.

“But they have the advantage of surprise,” Graystripe muttered. “They know we’re coming.”

“And we don’t know where they’re hiding,” Dustpelt finished.

Brightheart left her work at the barrier and padded into the clearing. Spiderleg, Berrynose, and Honeyfern joined her, ears pricked and tails flicking nervously.

“We know which way they headed,” Cloudtail meowed. “One group went up toward the top of the territory, one went down toward the lake, and it looks like one doubled back and headed for the old Twoleg path.”

“How in the name of StarClan did they know which way to go?” Dustpelt wondered.

Firestar frowned. “It looks like they know our territory better than we imagined.”

“That’s impossible!” Brambleclaw insisted. “Our patrols have kept them from crossing the border.”

Lionpaw listened silently, his belly churning as he pictured WindClan warriors creeping night after night from the fox hole, past the patrols, and into the very heart of ThunderClan territory to scout for places to fight.

The thorn barrier shook as Whitewing charged into the camp. “No sign of trouble on the ShadowClan border!”

Brackenfur and Hollypaw raced in after her, Icepaw and Sorreltail on their heels.

Firestar faced them. “WindClan have split up and are still on our territory.”

Hollypaw’s eyes widened.

“They didn’t leave?” Sorreltail gasped.

“No.” Firestar paced the clearing. “We need three battle patrols to go out and find them. A fourth patrol will stay behind to defend the camp.” He swung his head toward his old friend. “Graystripe, that will be your duty.”
