Enola Holmes:the cryptic crinoline

I liked "The cryptic crinoline" allot.In this Enola Holmes mystery.Enola's half deaf land lady "Mrs.Tupper" has been kidnapped,Enola's first lead was to find Mrs.Florince Nightingale the famous "Lady with lamp" from the Crimean war but what enola cant figure out is how does Mrs.Tupper get into all of this.The book was great.
