When we got to the supermarket, a police officer stopped us right before we ducked underneath the caution tape.

"Boys," he said. "This tape says 'Crime Scene. Do Not Cross.' What about that do you not understand? I'm sorry, you can't go in there."

"Newbie, right?" Sherlock asked. The police officer gave the affirmative. "Well, Officer, you'll soon get used to me being around. I've solved a record amount of crimes for this police department. So if you'll excuse me…"

Sherlock brushed right past the befuddled officer. "Sorry, sir," I said as I walked past him as well. "He's usually like that."

When we got to the back of the store, almost everything was the same except for there was no body. "Oh come on!" Sherlock exclaimed, exasperatedly. "It's not like I'm a little kid or something! I'm 13 for heaven's sake!"

Inspector Lestrade turned around and walked over to us. "Sorry Sherlock, but the rule is that you can't work with a dead body until you are legally able to be a part of the police force," he said.

"Picture's please," Sherlock said with resignation. Inspector Lestrade gave them to him with a grin.

"Be careful they're graphic," Inspector Lestrade said with a smirk.

"Very funny." Sherlock took out his notebook and pored over the pictures for a few minutes, making little notes in the notebook. "Hmmm, this is a very interesting case. Already the murderer has made a few mistakes. First, he used his own handwriting to write this note. Second, and this proves that he obviously never took Murder 101, he left behind the murder weapon. I'd say that this knife is new, maybe bought a day or two ago. We go to all the local shops, ask around, we find our murderer hopefully before he hurts anyone else. Although I do have to say that it would be very interesting to have a serial killer on our hands."

Yeah, Sherlock thinks serial killers are interesting.
