The Case of the Left-Handed Lady

London, January 1889. Enola, fourteen, hides from her worried brother, Sherlock, until Dr. Watson consults her imaginary identity, the Perditorian Dr. Ragostin.

As Mrs. Ragostin, Enola seeks Lady Cecily, sixteen, who vanished in her nightgown, leaving a ladder at the window, bold charcoal sketches, and mirror-writing diaries about the East End poor.
