A letter to Jane Bromley had been addressed incorrectly, and she could not be located. Therefore, the letter was returned to the Post Office, where it was opened. The letter inside had been placed there by mistake, and was a letter from a gentleman in Eaton Place to his son, who appeared to be an officer in the army. The writer of the letter, who is not identified, went on to say that he could not help suspecting General Brown of being the Whitechapel murderer. The suspicious letter was passed on to the police, who interviewed and cleared General Brown. The source of the suspicion against General Brown appears to have been a lady who witnessed him operating on a race horse, and had jumped to the conclusion that he would not shirk at anything, presumably even murder. It is possible that she may have subsequently passed her suspicion regarding General Brown on to the unnamed letter writer.
