The Mystery of a Hansom Cab

In the dead of night on a lonely Melbourne street, a cabbie discovers to his horror that his drunken passenger has been murdered - poisoned with a chloroform-saturated handkerchief. The killer, his motive, and even the victim's identity are unknown. The last person to be seen in the victim's company cannot be identified and has vanished into the streets of the Australian metropolis. The solution lies within a labyrinth of dark secrets, missing papers, evasive witnesses, and a deadly game of blackmail.
