With a wink to the original Holmes this is a solid mystery. Written from the standpoint of the sidekick Watson. He moves to NYC and tries to befriend Shelby. She needs some practice being friends but John doesn't give up on her. She doesn't do much to redeem herself either. Readers will enjoy figuring out the mystery more than the characters. However the original Sherlock was always written to be pompous and annoying right. Wished there had been more illustrations to help story along. Still a good choices for 5th grade readers.
