Our attention was first called to this girl when a number of court people were trying to solve the mystery. She had been arrested for shoplifting and her curious attitude and statements had made some believe she was not quite right mentally. Once before she had been detected stealing things in a shop. One of her remarkable statements this last time was that her parents were implicated in the thieving and she named certain stolen articles which might be found at their home. She went with the detectives and accused her ``mother'' of wearing a dress which she, Edna, had stolen. The woman was forced to give up the dress and other articles, but it was found later that these goods had been actually bought and paid for by the parents. Later it was found that the woman was a party to the girl's stealing and this made the girl's story seem all the more strange, for if she were going to involve the people at all why did she not pick out the actually stolen articles? However, long study of the case brought out the fact that this type of statement was a characteristic of Edna's. Her word on even important points was absolutely unreliable and her own interests were frequently thwarted by her prevarications. The case in its different aspects came up in court again and again until finally most of the truth was ascertained, enough to justify radical measures being undertaken. During this period the mother was discovered to be an atrocious liar; even with her last bitter confession that all she had said about her motherhood had been untrue, she manufactured more quite unnecessary falsehoods. In the meantime the family physician and the family lawyer had both informed me of the peculiar mysteries of the case and of the perfect mass of lies into which the statements of both mother and daughter led. This sort of thing had been going on for years. It is of no small interest to note that the woman was greatly over-dressed and made up. On numerous occasions she appealed to us to study the girl and find out why she lied so much and why she had such an inclination to steal, in the meantime attempting to fill us up with many inventions about the girl's antecedents.
