The Case of the Peculiar Pink Fan (Enola Holmes #4) by Nancy Springer
When Enola Holmes encounters her friend Lady Cecily hiding behind a pink fan, she finds it peculiar. Cecily is being held hostage in an abysmal orphanage, forced into a miserable marriage. Enola joins forces with the much older famous brother Sherlock who she has fought desperately to elude, and risks her own freedom to rescue her friend.
Dog Gone Note: We have book 1 of the Enola Holmes mystery. Just use the "Search" function adding the author's name. The dust jacket has a slight tear in the upper corner. This book is in very good condition (it would be in excellent condition without the tear).
