G. Baxter & Flint Case

G. Baxter & Flint, Private Investigators, are on the up-new offices and at times, more cases than they can handle. The Strange Case of Lizzy Croft, however, is one case they could have done without. The woman is either an accomplished liar or a mass murderer. Flint doesn't know what to do for the: report her to the police or send her packing. He considers the possibility she is playing games, making things up as she goes along, but if so why? Is the woman insane, or devious? Flint must do, something, but what? To do nothing is out of the question.

Mad, devious, or an accomplished liar? Which of these can Mrs. Croft be?
