Historical text, verbatim:25 Sept 1888 Dear Boss, 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 ears 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. Good Luck. Yours truly Jack the Ripper Dont mind me giving the trade name PS Wasnt good enough to post this before I got all the red ink off my hands curse it No luck yet.

What the sources say about receipt (1)
Historical text, verbatim:Commonly used name for a letter sent to the Central News Agency, 5 New Bridge Street, London EC, in September 1888 which claimed to be from the Whitechapel Murderer. Dated 25th September, it arrived at the News Agency offices on 27th September. It was written in red ink, covering both sides of the paper and was followed by a post-script written in red pencil/crayon. The envelope was addressed to 'The Boss, Central News Office, London City', was postmarked 'SP 27 88' and was posted from 'London EC'.
Established facts
- Well supported Retrieved A letter dated 25 September 1888, beginning "Dear Boss", written in red ink and signed "Jack the Ripper", was delivered to the Central News Agency on Thursday 27 September 1888. It threatened that "The next job I do I shall clip the lady's ears off".
- Well supported Retrieved The printed 1888 texts of the 'Dear Boss' letter differ in small ways. The Daily Telegraph has "whores" and "Great joke about Leather Apron. Gave me real fits"; the Daily News prints "---" and the Evening Standard "_______" for "whores"; the Evening News has "rare fits" and "just for folly". The Casebook transcription of the original reads "That joke about Leather Apron gave me real fits" and "whores".
- Weakly supported Retrieved The name "Jack the Ripper" reached the public when the 'Dear Boss' letter was printed by London papers on 1 October 1888. The Casebook Wiki says it was "generally accepted" as the first use of the name.
Authenticity: the disputed claims
Supports the claim (3)
Historical text, verbatim:On 27th September a letter was received at a well-known News Agency, addressed to the '' Boss.'' It was written in red ink, and purported to give the details of the murders which had been committed. [...] This document was sent to Scotland Yard, and (in my opinion most unwisely) was reproduced, and copies of same affixed to various police stations, thus giving it an official imprimatur. In this ghastly production I have always thought I could discern the stained forefinger of the journalist — indeed, a year later, I had shrewd suspicions as to the actual author [...] gruesome stuff, it is certain to my mind that it was not the mad miscreant who had committed the murders.
Historical text, verbatim:Thomas Bulling himself has also been accused of being the creator. This information was brought to light by the discovery of the Littlechild Letter in 1993[12] which stated that: With regard to the term 'Jack the Ripper' it was generally believed at the Yard that Tom Bullen [sic] of the Central News was the originator, but it is probable Moore, who was his chief, was the inventor. It was a smart piece of journalistic work. No journalist of my time got such privileges from Scotland Yard as Bullen.
Historical text, verbatim:Despite being generally accepted as containing the first use of the name 'Jack the Ripper'[6], opinion on its veracity weighs heavily in favour of it being a contemporary hoax, most likely written by a journalist. Robert Anderson believed this to be the case, stating so in his memoirs[7] as did Melville Macnaghten:
Qualifies the claim (1)
Historical text, verbatim:On Thursday last the following letter, bearing the "E.C." post-mark, and directed in red ink, was delivered to the Central News Agency: Sept. 25, 1888. Dear Boss - I keep on hearing the police have caught me, but they won't fix me just yet. I have laughed when they look so clever and talk about being on the right track. Great joke about Leather Apron. Gave me real fits. I am down on whores, and I shan't 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 can't use it. Red ink is fit enough, I hope. Ha, ha! The next job I do I shall clip the lady's ears 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. Good luck - Yours truly, JACK THE RIPPER. Don't mind me giving the trade name. 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! The agency says: The whole of this extraordinary epistle is written in red ink in a free, bold, clerkly hand. It was of course treated as the work of a practical joker, but it is singular to note that the latest murders have been committed within a few days of the receipt of the letter; that, apparently, in the case of his last victim the murderer made an attempt to cut off the ears; and that he actually did mutilate the face in a manner which he has never before attempted. [...]
Later assessments in the sources (5)
Historical text, verbatim:The 'Dear Boss' letter had apparently gone missing from the official files by 1928. It was later believed to be in the possession of Gerald Donner, the grandson of Melville Macnaghten and was seen at his home by Philip Loftus in 1950[14]. After Donner's death, the letter went missing again but was sent anonymously to Scotland Yard in a brown envelope (posted from Croydon) in November 1987. The letter was accompanied by other material including Bulling's covering note, the envelope, Thomas Bond's post-mortem report on Mary Jane Kelly and documents relating to other criminal cases[15]. The Ripper-related documents were subsequently placed in the Public Record Office (now the National Archives) in Kew where they are in file MEPO 3/3153. Public access is limited owing to the 'iconic' status of the original Whitechapel Murders files and ephemera. [...]

Historical text, verbatim:The letter was not the first missive claiming to be from the killer (a letter dated 24th Sept was received earlier by Sir Charles Warren - see 24 September Letter). It was initially treated as a joke, but was passed on to Scotland Yard on 29th September with a covering note from Thomas Bulling of the Central News Agency: The editor presents his compliments to Mr. Williamson & begs to inform him the enclosed was sent the Central News two days ago, & was treated as a joke.[2]

What the sources say about receipt (1)
Historical text, verbatim:Colloquial name generally given to a postcard received by the Central News Agency on the morning of 1st October 1888[1]. It was a pre-stamped card in common use at the time, however the copying method of the Victorian era failed to register the blue colour of the printed 'stamp' and thus it does not appear on the various copies now available. Both message and address were written in red pencil/chalk. Both sides of the postcard were smeared with what appeared to be blood, the address side bearing traces of finger or thumb prints. It was addressed to 'Central News Office, London City E.C' and postmarked 'LONDON OC 1 88'.
Established facts
- Well supported Retrieved A postcard signed "Jack the Ripper", written in red and referring to a "Double event this time" and "Number one squealed a bit", reached the Central News on the morning of Monday 1 October 1888. The press gives the stamp as "London, E., October 1"; the Casebook Wiki gives the postmark as 'LONDON OC 1 88'.
- Well supported Retrieved The press texts of the postcard differ: the Star, Evening News and Times print "codding", the Daily News "coddling"; the Wiki transcription reads "codding".
Authenticity: the disputed claims
Supports the claim (2)
Historical text, verbatim:The Saucy Jacky postcard has often been cited in the past as potentially genuine on account of it being received on the morning of the day after the 'Double Event', which by modern standards suggests it was posted before the news was common knowledge. If this is to be accepted, then the Dear Boss Letter may also be considered genuine. Realistically, this is hardly the case. Knowledge of the 'double event' would have been widespread throughout the day of the murders, 30th September. Also, the postal service in the Victorian era was considerably more efficient (by necessity) than today, with many more collections which included Sundays. The postcard could easily have been written on the 30th September and posted in plenty of time to arrive at the Central News Agency on the 1st October.
Historical text, verbatim:A practical joker, who signed himself "Jack the Ripper," wrote to the Central News last week, intimating with labored flippancy that he was going to commence operations again in Whitechapel shortly. He said he would cut the woman's ears off to send to the police. This morning the same agency received a postcard smeared apparently with dirty blood. It was written with red chalk. It says: "I was not codding dear old Boss when I gave you the tip. You'll hear about saucy Jacky's work to-morrow. Double event this time. Number one squealed a bit. Couldn't finish straight off. Had not time to get ears for police. Thanks for keeping back last letter till I got to work again. - JACK THE RIPPER."
Qualifies the claim (1)
Historical text, verbatim:The Central News says: A post-card bearing the stamp "London, E., October 1," was received this morning, addressed to the Central News Office, the address and subject matter being written in red, and undoubtedly by the same person from whom the sensational letter already published, was received on Thursday last. Like the previous missive, this also has reference to the horrible tragedies in East London, forming, indeed, a sequel to the first letter. It runs as follows: "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. Had not time to get ears for police. Thanks for keeping last letter back till I got to work again. "JACK THE RIPPER." The card is smeared on both sides with blood, which has evidently been impressed thereon by the thumb or finger of the writer, the corrugated surface of the skin being plainly shown. Upon the back of the card some words are nearly obliterated by a bloody smear. It is not, necessarily assumed that this has been the work of the murderer, the idea that naturally occurs being that the whole thing is a practical joke. At the same time the writing of the previous letter immediately before the commission of the murders of yesterday was so singular a coincidence that it does not seem unreasonable to suppose that the cool, calculating villain who is responsible for the crimes has chosen to make the post as medium through which to convey to the Press his grimly diabolical humour.
Weakly supported Retrieved In 1888 the postcard was taken to be by the same writer as the 'Dear Boss' letter: the Central News said so, and The Times reported that "No doubt is entertained" of it. The Casebook Wiki says the handwriting matches the letter's postscript.

Historical text, verbatim:Two communications of an extraordinary nature, both signed "Jack the Ripper," have been received by the Central News Agency, the one on Thursday last and the other yesterday morning. The first - the original of which has been seen by Major Smith, the Assistant Commissioner of the City Police - was a letter, bearing the E.C. postmark, in which reference was made to the atrocious murders previously committed in the East-end, which the writer confessed, in a brutally jocular vein, to have committed; stating that in the "next job" he did he would "clip the lady's ears off" and send them to the police, and also asking that the letter might be kept back until he had done "a bit more work." The second communication was a postcard, and as above stated, it was received yesterday morning. It bore the date, "London, E., October 1," and was as follows: - "I was not codding, dear old Boss, when I gave you the tip. You'll hear about Saucy Jacky's work to-morrow. Double event this time. Number One squealed a bit; couldn't finish straight off. Had not time to get ears for police. Thanks for keeping the last letter back till I got to work again." The postcard was sent to Scotland Yard. No doubt is entertained that the writer of both communications, whoever he may be, is the same person.

- Addressed “Dr. Openshaw, Pathological curator, London Hospital, Whitechapel”
What the sources say about receipt (1)
Historical text, verbatim:Alleged communication from 'Jack the Ripper', sent to Dr. Thomas Horrocks Openshaw at the London Hospital on 29th October 1888. Dr. Openshaw had recently analysed the Lusk Kidney which had been sent - along with the Lusk Letter - to George Lusk of the Whitechapel Vigilance Committee on 16th October. The envelope was addressed to 'Dr. Openshaw, Pathological curator, London Hospital, Whitechapel' and was postmarked 'LONDON E', 'OC29 88'. [...] The Openshaw Letter was in the possession of former City Police Officer and author Donald Rumbelow until 2001 when he donated it to the Public Record Office (National Archives). A copy of it is on display with other Ripper-related items in the Royal London Hospital's museum in Newark Street, Whitechapel.
