The workings of Janet's mind in connection with her alterations of a story were sometimes most curious. We were interested to study a long letter quite coherently written to her mother a few days before we saw the young woman, and about the time when she first told her long story to the department manager. In the letter she spoke of the extraordinary opportunities she now had in this place of employment, exaggerating her salary to $14 a week. She stated she had already had a raise, and could get work for other members of her family at good salaries. She was about to start a bank account, and so on. But instead of making any remittances to her mother (such as she asserted at one time) she requested her parents to send her $5 to tide her over. We counted no less than nine definite falsehoods in this epistle. We were keen to know if Janet could remember her own prevarications and so asked her if she could recall what she had written to her mother. She trimmed her statements most curiously then, being aware we knew her salary to be $8 a week. She said she had told her mother her salary was $10, but in answer to our reply, ``Oh, you said more than that,'' she blurted out, ``Well, I said $14.'' It was quite evident she remembered this, as well as certain other exaggerated statements and figures in the letter. We were fortunate enough to be able to analyze out much of the genesis of this girl's career as a pathological liar. After the immediate situation was somewhat cleared and Janet asserted she was anxious to make a new start in life, we began our inquiry into beginnings. Janet showed willingness to enter into the question of her mental antecedents and tendencies which she maintained she heartily deplored. To be sure we had evidence that even in her most sincere moments she was unable to refrain from occasional falsifying, but the main facts seemed self-evidently true, and some of them were corroborated at interviews with the parents.
