Okay, let me start off by telling you that the cover of the edition I read is a LIAR. The blurb reads "What if Sherlock were the boy next door?" NO! No! I am creating a character image in my mind and you're ruining it! It should read, "What if Mycroft, Sherlock's equally smart older brother, were the boy two doors down (by the way forget we even used the name Sherlock, he's not in this book)"
Have the proper image in your mind now? Good. Mycroft is a smart, bored, and rebellious teen. He is friends with Watson ("Watts"), a country girl, recently forced to move into the crowded, smelly, city. They come across the murder of a homeless man they knew and decide they owe it to Homeless Dave to solve his murder. What ensues is a great, teen, murder mystery, characters with actual depth and back-story, believable behaviors, and tolerable, dare I say it, likable romance. Yes. No dreaded love triangles, but the budding romance between Watts and Mycroft is adorable and well done. I won't say that very often, so take heed! This was an all-around great book!
