Received on September 27th, 1888 at the Central News Agency, this letter was originally believed to be just another hoax. Three days later, the double murder of Stride and Eddowes made them reconsider, especially once they learned a portion of the latter's earlobe was found cut off from the body, eerily reminiscent of a promise made within the letter. The police deemed the "Dear Boss" letter important enough to reproduce in newspapers and postbills of the time, hoping someone would recognize the handwriting.
A postcard received at the Central News Agency on October 1st, making direct reference to both the murders and the "Dear Boss" letter, is believed to have been written by the same hand. It is reproduced below.
Whether or not the letter is a hoax, it is the first written reference which uses the name "Jack the Ripper" in reference to the Whitechapel murderer.
I keep on hearing the police have caught me but they wont fix me just yet. I have laughed when they look so clever and talk about being on the right track. That joke about Leather Apron gave me real fits. I am down on whores and I shant quit ripping them till I do get buckled.
Grand work the last job was. I gave the Lady no time to squeal. How can they catch me now. I love my work and want to start again. You will soon hear of me with my funny little games. I saved some of the proper red stuff in a ginger beer bottle over the last job to write with but it went thick like glue and I cant use it. Red ink is fit enough I hope ha. ha.
The next job I do I shall clip the ladys ear off and send to the police officers just for jolly wouldn't you.
Keep this letter back till I do a bit more work, then give it out straight.
My knife's so nice and sharp I want to get to work right away if I get a chance.
Yours truly, Jack the Ripper. Don't mind me giving the trade name. PS Wasn't good enough to post this before I got all the red ink off my hands curse it No luck yet. They say I'm a doctor now. ha ha."
