Be careful. We are being watched.

That's the message Enola Holmes gets from her friend Lady Cecily, who uses her pink fan to signal danger. Enola must save Cecily, who is being held prisoner in an abysmal orphanage. If Cecily isn't rescued, she'll be forced into a miserable marriage! But Enola's brother Sherlock is the only one who can help. If she joins forces with Sherlock, Enola risks her freedom, but if she doesn't, Lady Cecily may be doomed!
