Sherlock Holmes vs. Jack the Ripper Hints

What "incongruous detail" is Holmes wanting me to point out?

  • 1 of 5: He said that we were able to establish it regarding the Hanbury Street murder. What's similar here?
  • 2 of 5: Not the cuts on the throat. It's something that seemingly has little or nothing to do with the murders.
  • 3 of 5: He's referring to the personal items found next to each victim.
  • 4 of 5: In this case, that item is the bag of pastilles.
  • 5 of 5: Click on the chalk outline's hotspot to get a close-up, then pick up the magnifying glass and click on the bag of pastilles.
