All four books in 'Monster Files', a series of children's mystery books by A.E. Stanfill, now in one volume!

It Lives Under My Bed: Imagine being the new kid in town, with no friends and just moved into a creepy house. Strange things are happening, and you don’t know why. This is what's happening to Bryan Sanders, and that’s where Miller and Smith come in. They’re the founders of Monster Files; the only ones willing to listen and help Bryan out. Miller believes the whole town of Manila, Arkansas, is surrounded by the supernatural. And it only happens to the kids, not the adults: that's why not a single adult will listen, and that's why Monster Files was started. This is their first real case, and Miller will do everything he can to help Bryan figure out what is under his bed. But is one of them hiding something?

My Neighbor Is A Werewolf: Miller and Smith are helping a girl named Amber, who believes her neighbor is a werewolf. After Miller goes on a stakeout with Amber, they find out the man has plenty of secrets. For one, he seems to have a taste for cats. And possibly the neighborhood kids as well. The full moon is shining bright, and something strange is afoot in their small town. But can The Monster Files stop the werewolf before he takes another into the darkness?

Ghostly Park: Miller is on his way to Summer Camp and he is leaving Smith in charge. On top of that, Smith has done something she swore she would never do: joining the track team. Smith's summer takes a turn to the strange side, as she meets a young boy named Charlie. He warns her to stay far away from the park before she ends up like the others. Things keep getting weirder every time Smith goes to the park so she decides to investigate it, and Charlie. But is there some lost secret in the park? Is the place haunted, or is it all just a big prank?

Big Ben The Mean Guinea Pig: Justin has always wanted a pet. A dog a cat even a turtle would work. His parents would always tell him no; he wasn’t responsible enough for that yet. Until one day his Mom and Dad agreed to take him to the pet store. That’s when Justin saw him: a guinea pig that was different from all the others. Colors, fur, looks and all. That was the one Justin wanted, and that was the day his life would change forever.
