In the third book of the series, Enola Holmes is back on the job in three new mysteries! Now fully independent, Sherlock Holmes' much younger and feistier sister leads the case in this beautifully drawn graphic novel based on Nancy Springer's bestselling mystery series.

15-year-old Enola Holmes is on her own now, working as a scientific perditorian (a finder of persons and things) in Victorian London in her own secret office. Enola puts her skills to the test once again when three sudden disappearances shake her world.

A woman appears on the Holmes' doorstep, insisting her twin sister is still alive and missing despite her husband declaring her dead. Enola's old friend Lady Cecily vanishes into London, and she must find her before she's returned to her boor of a father. And when a publisher goes missing and his friend refuses to work with a young woman, Enola goes head to head with her famous brother Sherlock.

Book Three contains three engaging mysteries: The Case of the Black Barouche, The Case of the Elegant Escapade, and The Case of the Mark of the Mongoose.
