Nah, the woods are pretty boring today: plants, bugs, birds, there's a squirrel over there throwing earth at something that glints in the sun...

Great.

Well, it's shiny. Could be valuable even if it's not cool.

He claps his hands loudly. Squirrels don't like loud noises, right? 

This squirrel is apparently bolder than most. It stares at Stiles for a second, scratches its nose, then back to burying the shiny thing in dirt.

He kicks the squirrel. 

What's the thing?

The squirrel dodges the kick and runs away. What a mean human.

The thing... looks like the corner of a book. It's too deeply buried for anything more detailed than that to be made out.

Can he just bend down and yank it really hard? 

He will probably fall on his butt if he tries but he will successfully dislodge the book from the dirt!

Well. Nobody has to know. He'll tell Scott he had to climb a tree.

Does it look old or interesting? 

It looks like this, plus or minus lots of dirt.

Yeah, kind of interesting. Who leaves a book in the woods?

Scott will definitely want to see this.

Stiles hides the book inside his jacket and jogs to his bike.

And later, Scott answers the knock at his window.

"Careful, my mom will hear you if you knock over my lamp again."

"Yeah, yeah." 

He tosses the book in, and scrambles through the window.

He only hurts himself when he lands on the floor.

"You got me a book?"

He runs his fingers along the spine.

As he handles the book it—clicks open. Of its own accord.

"Stiles, the book has some kind of lock. I think I broke it. It must be really old." 

He opens it.

Stiles peers over his shoulder. 

Inside the book a rectangular hole is cut into the pages, and in it—

—a deck of cards.

"Wow. Usually when books lie to you they wait until you're past the cover page. We probably can't even sell this."

Scott ignores him and starts flipping through the deck. 

There are several cards! Fifty-two of them, to be precise, with drawings and strange names, in a somewhat tarot-y fashion.

"This is kind of weird. Where'd you get it?"

"It was stuck up a tree in the middle of the woods. There were some birds nesting but I was pretty careful not to bother them."

"Who leaves a bunch of cards in a hollowed-out book in the middle of the woods?"

"Look kind of like Tarot cards. Maybe someone was trying to cast a spell or something and we interrupted it."

"Maybe. I think it's probably something valuable and we should turn it in."

He holds the deck in his hands, turning it over to examine the design.

"What are Tarot cards like?"
