It's been one-hundred years since Watson died and Mycroft still doesn't understand what Sherlock saw in having such a companion, but after so long alone and somehow still as young, he is starting to wonder what it might be like to have a disciple of his own. Life for Amelia Jones is dull, she's spent all her years writing about the adventures other people have, and then she meets the Holmes brothers. Can she persuade the most intelligent person in the world to trust her? And if she does, can she survive the danger that surrounds them?
