The Capricorn Stone (Madeleine Brent Series, Bk. 2)

Bridie Chance has been brought up in luxury, but her world is shattered when she is told that for thirty years her much loved father has been a highly-successful criminal - and is now dead. With no home, no friends, and almost no money, Bridie finds herself responsible for a helpless mother, a younger sister and an elderly nanny - a crushing burden for a girl of twenty at the turn of the twentieth-century. Then come the new friends and the enemies, and how can she know which is which amid the mysterious events which gradually close in about her?
