Acclaimed author Elizabeth Eulberg continues her hilarious middle-grade twist on Sherlock Holmesas detective duo Shelby and Watson tackle their trickiest case yet--going undercover . . . as figure skaters!

Being friends with a super sleuth isn't easy, especially when she's nine years old, four feet tall, and full of attitude. But for eleven-year-old John Watson, being friends with Shelby Holmes is just the adventure he's looking for.

After Watson's online journal chronicling his and Shelby's case-closing abilities attracts the attention of a newspaper reporter, the pair becomes a small "media sensation" in their Harlem neighborhood. So it's no surprise (at least, to Shelby!) when the article lands them a new client--a figure skating coach whose star athlete, Jordan Nelson, is receiving strange, threatening messages, written entirely in code.

There's no one better to crack the cipher than dynamic duo Shelby and Watson! But to gather information, Shelby decides that they'll have to go undercover . . . as an award-winning pair skating team. Can they use the laws of physics and their acting skills to maintain their covers and figure out who's sending Jordan such strange messages before it's too late?
