Ice Wolves

You take the right hallway, Bob and James behind you. You choose a random door and knock it open with your weight. Inside are some people, who scream when they see you. "Shhh!" you say. "They're coming! We have to hide!"
"Who the hell are you?" says a man.
"I am Zachary Letman," you reply.
"I am Jon," he tells you. "Who is after you?"
"I can't tell you," you say.
"Why not?" he asks.
"Because I don't have enough time. You are about to find out."
Sure enough, seconds later, you see a snout peek from the side of the door. It then disappears, and you hear footsteps leading away from the door. You sigh in relief and turn to the couple. "What is it?" the man demanded.
"You are not going to believe me, but there are werewolves on our trail."
"I believe you," said the man. "Judith and I came here to find evidence of werewolves for our new television show, Legends. How did you first meet them?"
You open your mouth to reply, but suddenly, the window bursts open, and a clawed, hairy hand grabs James. "Help me!" he screams as the figure tries to pull him outside.
You run to him, pulling his legs, but your opponent is too strong, and James is pulled through the window. You hear his screams echoing through the black. Only you, Bob, Judith, and Jon remain. "If I didn't believe you then, I believe you now," Jon admitted.
You sit on the floor and sigh. You have lost. All of you will die. However, suddenly, you remember. "My knife!" you say. "It is made of silver! There is only one problem."
"What is that?" asked Bob.
"I don't know where it's at!" you say.
"We have to find it!" screamed Bob. "It's our only chance!"
