Enola Holmes and the Elegant Escapade

Enola Holmes, Sherlock's much younger, and feistier, sister, returns in an adventure of a confused young Baronet's daughter who is on the run from her father's devious schemes in Nancy Springer's Enola Holmes and the Elegant Escapade.
Enola Holmes, the much younger sister of Sherlock, is now living independently in London and working as a scientific perditorian (a finder of persons and things). But that is not the normal lot of young women in Victorian England. They are under the near absolute control of their nearest male relative until adulthood. Such is the case of Enola's friend, Lady Cecily Alastair. Twice before Enola has rescued Lady Cecily from unpleasant designs of her caddish father, Sir Eustace Alastair, Baronet. And when Enola is brusquely turned away at the door of the Alastair home it soon becomes apparent that Lady Cecily once again needs her help.
Affecting a bold escape, Enola takes Lady Cecily to her secret office only to be quickly found...
