Icepaw scampered to her mother’s side. “I’ll be strong and brave too!”

Ferncloud touched her muzzle to the little cat’s ear. “I know.”

“Lionpaw!” Firestar called from the mouth of the thorn tunnel. His patrol was already filing out into the forest.

“Good luck!” Lionpaw whispered to Hollypaw and Jaypaw before running out of the camp after his Clanmates.

Firestar led them quickly through the woods, keeping to the undergrowth. No cat spoke as they moved through the bushes. In the darkness, Lionpaw stumbled over roots and tripped on stones. They were heading into battle, but the familiar tingle of excitement was dulled by worry. What if his hunch was right? Had WindClan really been sneaking through the fox hole he’d discovered?

Berrynose was jostling behind him, but Lionpaw refused to let him pass.

“Mouse dung!” The cream-colored tom suddenly cursed.

Lionpaw turned to see him hopping about, flapping his paw.

“What happened?”

“A dumb mouse hole tripped me.”

“Are you okay?”

Berrynose pressed his sore paw carefully to the ground, then sighed with relief. “Nothing sprained.”

The rest of the patrol had pushed on ahead.

“We’d better catch up,” Lionpaw whispered.

He quickened his pace, glancing back to make sure Berrynose was keeping up.

The scent of WindClan soured the air. Worse, it was growing stronger as they neared the border, until it seemed every leaf and twig were tainted by their stench. Lionpaw’s heart was racing. Why hadn’t he done something about the tunnel? He should have told Firestar, or blocked it up.

An angry yowl made him jump.

“The fox-hearted cowards!” Firestar was furious.

Lionpaw burst from the undergrowth to see the ThunderClan leader standing at the edge of the thicket where the fox hole lay concealed. The patrol gathered around it and, even in the moonlight filtering through the trees, the WindClan paw prints were obvious. The forest floor had been trodden to mud by the comings and goings of the WindClan intruders.

“They must have been using this for ages!” Ashfur growled.

Firestar stooped to sniff the prints. “They used it tonight; that’s for sure.”

Spiderleg was squeezing out of the thicket, using the same gap Lionpaw had wriggled through days earlier. “There’s a tunnel in here,” he confirmed. “I didn’t go down too far, but it stinks of WindClan, and leads toward their territory.”

“Then we must block it up,” Firestar ordered. “No more WindClan warriors will be coming in this way.”

“Or leaving,” Ashfur hissed.

Poppyfrost glanced around nervously. “But they’re here already.”

“Then we’ll deal with them next,” Firestar promised. He grabbed a dead branch in his jaws and rammed it into the gap in the thicket. “We can seal off the entrance to the tunnel later,” he meowed. “Blocking this opening should be enough for now.”
