[The Wollstonecraft Detective Agency 02] • The Case of the Girl in Grey

This history-mystery series continues with another fine display of brains and bravery from the Wollstonecraft Girls—Ada Bryon Lovelace and Mary Shelley. The Wollstonecraft Detective Agency was supposed to be a secret constabulary, but after the success of their first case ( The Case of the Missing Moonstone ), all of London knows that Lady Ada and Mary are the girls to go to if you have a problem.

Their new case is a puzzle indeed. It involves a horrible hospital, a missing will, a hasty engagement, and a suspiciously slippery servant. But Mary has stumbled onto a mystery of her own. She spotted a ghostly girl in a grey gown dashing through the park. A girl who is the spitting image of their new client.

The two cases must be linked . . . or else there’s a perfectly supernatural explanation.
