This is the “From Hell” letter, sent by Jack the Ripper to the president of the Whitechapel Vigilance Committee that was pursuing him. He included a bloody fragment to prove his identity:
“I send you half the Kidne I took from one woman and prasarved it for you tother piece I fried and ate it was very nise. I may send you the bloody knif that took it out if you only wate a whil longer”
Whoever he was, Jack certainly had a flair for dramatic horror. But much of his fame is really due to newspapers, which were becoming popular at the time. His crimes, which combined sex, violence, mystery, class warfare and police ineptitude, were tailor-made for cheap sensation. (In fact, it was probably a journalist who invented the “Ripper” nickname.)
Casebook: Jack the Ripper has gathered examples of lurid accounts from as far away as Poland, Jamaica, and Mexico. “All London is ringing with the horror of the thing,” writes one New Zealand editor. “The woman who reads, with hair standing on end, the details of some fresh outrage to-night cannot feel sure that on the morrow she may not be the next victim.” The whole episode is a low point for responsible journalism.
