Jack the Ripper - Short story

Jack the Ripper was an uncaught serial killer roaming the streets of London starting in 1888.

For a school assignment we had to do a crossover between Jack the Ripper and one of the books we read that year. I decided to do flight, in which the main character keeps seeing through the eyes of other people. He is seeing through the eyes of the last Jack the Ripper victim, Mary Kelly, the ripper has never killed after that as far as we know.
