The Great Shelby Holmes and the Coldest Case: 10/20/18
The Great Shelby Holmes and the Coldest Case by Elizabeth Eulberg is the third of the Shelby Holmes middle grade mysteries. Shelby and John are hired by an ice dancing coach who is worried because her star student has been receiving threatening notes in a cypher made up of stick figures who are ice dancing. The two go undercover to solve the mystery.
Immediately the ice dancer cypher brings to mind "The Adventure of the Dancing Men" (1903). It's one of the classics and can be found in The Return of Sherlock Holmes. It's also one of the rare ones where Sherlock can't keep his client alive. Thankfully the stakes are less high for Eulberg's characters and the client and her student survive!
With threatening notes being sent to a person in a competitive sport, I'm also reminded of The Mystery of the Midnight Rider (2013) by Carolyn Keene. Turns out the plot is more complex than the Nancy Drew Diaries one and is more akin to Espresso Shot by Cleo Coyle.
Simply put, Eulberg continues to adapt Sherlock Holmes for middle graders, making her mysteries complex and compelling but set in situations relevant to modern middle schoolers.
