Femme Fatale

Sherlene Holmes was not really born a Holmes. Heck, Mycroft was not really her biological brother.
Her own mother was actually pregnant with her as she was running from a pursuer around the time Mycroft's mother passed.
Sherlene wishes she could not carry her true title because of its dark legacy.
But when the Lord of Crime plunges the nobility into a new wave of fear, Sherlene must bring her true name and the Aristocrats of Evil back to the stage.

The Moriarty Brothers will learn why it's dangerous to play with a Phantomhive.
