Murder on the Ballarat Train by Kelly Greenwood (1991)

This is my third Phryne Fisher mystery and I could continue to gobble these up like tasty sweet morsels. Phryne is on a train with her assistant Dot, when she smells chloroform, manages to pull out her gun and shoot the window to get fresh air, opens all the windows, saves all her fellow passengers in the car, except an old lady that is missing, and of course later found dead, murdered. Phryne takes on the daughter of the missing woman, keeps her at her house until she is well, as she got burned by the chloroform on her face. Phryne also picks up a bright 12 year old girl, who doesn't remember who she is. So Phryne solves three mysteries in a span of a few days - the murder, who is the girl, and she finds another missing woman that was supposedly abducted by a decent looking gentlemen. Her sleuthing stops not just the murdered, but a few other criminals along the way. Of course she has to have a man or two to play with, and there are some young students that pique her curiosity. And her household grows with loyal folks. Wonder who she will take in/on next?
