The Art Of Murder headcanon thing?
The dog being revealed with mud and paper on him, while Sousuke is also mud covered. Leading the gang to believe he is the murderer.
The truth being revealed that he actually hitches a ride from the dog every night when he's first awake. He goes to the backyard where he practices his epic monologue he's going to give to the man who murdered his family. That night OC was "murdered" he got muddy. And when he returned inside and tried to wash it off, he got water on Pip as she was coming out of the book. The paper on the dogs paw was from the paper scraps Sousuke uses to lure the dog to the table so he can drop down.
