Though the murders are over a century gone, the Great Detective treated the victims as if they had cried out only yesterday. In the blood-soaked alleys of Whitechapel, he analyzed the case silently, as if he had put himself in the killer's shoes. "The Dear Boss letter is fake", he said, "As are most of the letters the public thinks are from the killer." With that in mind, the Great Detective was down 7 theories from his original 10. The From Hell letter was dissected like a living specimen. "Not a madman," he said, "but a message." He began speaking of patterns in the killings: surgical rhythm...an anatomical signature. From here he analyzed the three most prominent suspects: Montague John Druitt, Michael Ostrog, and Aaron Kosminski. "Druitt isn't Jack the Ripper," he said, "Yes he killed himself after the killer's last murder happened, but this rules him out. This is because Druitt was well educated, didn't have medical knowledge, and wasn't mentally insane." This meant that 1/3 suspects had been taken out. The Great Detective was close to solving the case. He later ruled out Ostrog as not being Jack the Ripper because his actions, although violent, didn't have the same intelligence or motive as the killer. This meant only Kosminski remained. This suspect was a barber who died in the Colney Hatch Asylum a year after Jack the Ripper's disappearance. Kosminski also suffered delusional and violent tendencies, as well as hatred for women, meaning he's the likely true Jack the Ripper. The Great Detective then theorized that it was actually the nurse of Kosminski at the Colney Hatch Asylum...but as it's almost impossible, the Great Detective used his method for deductive reasoning and concluded Kosminski was The Ripper.
