The first was written upon cheap notepaper in a cramped hand. Durgan, as he read, characterized the writer as a half-educated person, unaccustomed to social usage. It was dated from New York, and on a day about a month before the Claxton tragedy. It ran thus: "MRS. DURGAN: "Madame--I find the boarding-house to which you have been so good as to recommend me very comfortable. The parcel of comforts has reached and been duly received by me, for which also kindly receive my thanks. But I cannot forbear from reminding you that he who would seek spiritual knowledge and communion with those in a finer state of being than our own, must eschew such unnecessary gratification of the flesh.

For again I say that if we seek to know the spirit world we must purge ourselves of all dross. "I am, your obedient servant, "JOHN CHARLTON BEARDSLEY." "This is of importance", said Durgan. "He intended to go to the house on the fatal day, and there is suggestion of material for a quarrel over some unknown person--a woman, probably, as Mrs. Claxton's presence is required." "Is there reason to assume this third person unknown? It may have been a name that is erased, or it may have been a pronoun in the second person. Shall we read on?" The next letter was dated the day after the crime. It ran: "MRS. DURGAN:
