The Testament of Sherlock Holmes Hints

How many criminals were there?

  • 1 of 6: Examining all six of the footprints with the magnifying glass, you'll see that most of them are from hobnail boots like laborers wear.
  • 2 of 6: There's one print from a pair of well-worn shoes, plus one that's from an expensive pair of shoes, and that looks more recent than the others.
  • 3 of 6: Use the tape measure on all four of the hobnail boot prints to find that they're not all the same size.
  • 4 of 6: From that, you can deduce that two different criminals came in wearing hobnail boots.
  • 5 of 6: It's reasonable to assume that the well-worn shoes were also worn by a criminal, and that the expensive shoes were not.
  • 6 of 6: Therefore, there were three criminals.
