Murder on the Ballarat train

When Phryne Fisher arranges to go to Ballarat for a week, she eschews the excitement of her sporty Hispano-Suiza motorcar for the safety of the train. But as the passengers sleep, they are all overcome by chloroform poisoning. In the morning, Phryne is left to piece together the clues: a young girl suffering from amnesia, the body of an old woman missing her emerald rings, rumours of white slavery and black magic....the last thing Phryne was expecting of this train journey was that she will have to use her trusty Beretta .32 to save lives!
