Welcome to the Beat Hotel

The Beat Hotel was located at 9 rue Git-le-Coeur, which is in the famed Latin Quarter, not to far from the River Seine. It closed in 1963 because it was basically a death trap. The toilet was a hole in the floor that had to be shared with everyone on the floor. Some rooms had little light. It was infested with rats. Cleaning was irregular and it smelt terrible. One description said it was like something out of Naked Lunch.
The owner at the time to Beats moved in was Madame Rachou. Her husband, who owned the hotel with her, died before Allen Ginsberg, Peter Orvlovsky and Gregory Corso, the first really famous beats moved in. She ran a bistro on the first floor where she stood on an upturned casket because she was so short. The Beat Hotel was her kingdom, and she took great care in protecting them from the police. The only police that could get by where the immigration police, who would come once every three months, take whichever foreigner they wanted and make him or her pay a tax. This could be avoided by leaving the country every three months for Belgium or the Netherlands.
Despite the fact that the Beat Hotel was just about as dilapidated as you can get without it actually collapsing in around you, it had one advantage. Madame Rachou asked no questions about your personal life. In the book I have on the Beat Hotel, it said that one could bring anybody home "man, woman or group". They'd have to sign there name in the guest book if they where staying over, but nobody bothered much. Also, various eccentricities where excepted. One artist lined his walls with straw. One artist who was called Jesus Christ, painted on the walls and wore sandals even in winter. The Beat Hotel was also the early home of Chester Himes, an African-American most known for his series of Harlem detective fiction, in a time where other hotels greeted him with open racism and hostility for having a (younger) white girlfriend.
In the context of the series, the Beat Hotel is a sort of crossroads in time and space where artistic and magical activity is at it's highest. This is concentrated in the Beat Hotel, and it's inhabitants go on a creative voyage. This more or less happened with the Beats. Ginsberg wrote most of Kaddish, one of his most famous poems, and William S. Burroughs finished Naked Lunch and Nova Express here. Gregory Corso also wrote his very controversial Bomb. I'm attributing it to the fact the Beat Hotel from 1957-1963 was on an apex of space and time.
I'm not sure when Jack moved into the Beat Hotel. I know it was before most of the other characters. I know that he was stationed here to protect the Beat Hotel and because he was burned out from fighting oppressive secret societies and Lovecraftian monstrosities. He may have lived at the same there at the same time as Chester Himes, and worked on a few cases before. Jack also works on the security of the Organization in Paris in general. He is able to get a few residents of the Hotel to work with him, most notably Max Quincy, and most of his case work would involve his work within the Organization, trying to spread there ideals through various sources and keeping the balance between the Throne and the Tractate, as well as occasional cases taken by patrons to pay the rent.
