3 Sherlock Holmes Puzzles

As the introduction to Solving Sherlock Holmes commands: do not read this book; play it!

Throughout its pages are puzzles that Sherlock Holmes and Dr. Watson must solve. The puzzles react to famous characters, surroundings, and unusual events that were inspired by six classic Sherlock Holmes stories. For extra enjoyment, the plots have been slightly reimagined to add further mystery and purposely create more hurdles than Holmes and Watson had to overcome in the original stories.

Tune into your inner detective and sleuth out the answers to these three puzzles.

The Whistle Puzzle

There are 9 areas, which consist of 8 panes and the top. How can you place the numbers 1 to 9 in each separate area without the numbers touching their neighbors in any direction (for example, 8 cannot touch a 9 or 7; and 4 cannot touch a 5 or 3, etc.)?”  (Hint: there are a couple of solutions.)
