This Halloween is more than just tricks and treats--it's deadly serious.

It was supposed to be a simple ding-dong ditch. A dare to give them bragging rights. But as Sammy and her friends sneak up to the spookiest house in town, they get scared witless by a skeleton, and then witness something frightening enough to make even Sammy scream.

Things have taken a scary turn at school, too, with horrible Heather spreading embarrassing rumors about Sammy. Sammy devises a plan to expose her, but it's going to take a deceptive disguise, some good friends, and a lot of guts to...

It's Sammy's birthday, which should be a good thing, right? Not when her mom lets her cat out and now he's missing. Not when Sammy finds three dead cats while she's looking for him. And not when a psycho cat lady blames Sammy because one of the dead cats belonged to her.

Add a suspicious pro-wrestler named El Gato, a public cat-fight with her arch-enemy Heather, and a bombshell of a secret from...

In this adventure, Sammy is the one whodunnit--but will she get away with it?

Now Heather's in a major jam, and it feels almost fair--Heather has pinned more than a few crimes on Sammy. Besides, there are distractions galore to keep Sammy from confessing. Like the end of the school year. And the Farewell Dance. Especially the dance, since...
