Before she can start, however, the police arrive and arrest her client for the murder of his wife. There will be more murders and a vicious attack on Frances before she finally resolves a number of knotty questions. Is Hubert Sweetman really innocent? Where are his missing children? And who wielded the poisoned pen?
