The Wollstonecraft Detective Agency was supposed to be a secret constabulary, but after the success of their first case, 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.
