The "Saucy Jacky"Postcard
This letter was received on October 1st, 1888 at the Central News Agency. The handwriting is similar to that of the "Dear Boss" letter, and makes direct reference to both this letter and the murders of the previous night. Those who believe it to be genuine argue that the removal of Eddowes's ear (it was not taken away, nor mailed to the police) and the fact that the postcard mentions the double-event before it was described by the press both testify to its authenticity. Others believe a hoaxer could have gleaned details of both the previous letter and the murders in an early morning paper of October 1st.
"I was not codding dear old Boss when I gave you the tip, you'll hear about Saucy Jacky's work tomorrow double event this time number one squealed a bit couldn't finish straight off. ha not the time to get ears for police.
