Hi, I am Inspector Cachet and I am here to help you with your detective skills. 
This lesson is about problem-solving. Some cases are all about needing the mental skills to solve a complex problem and just about when you think you have solved it, there is another puzzle in front of you to solve until finally, you have cracked the case. Of course, you may have done too much work afterward, but that is how it goes sometimes.
The puzzle
All I got for you is this mysterious picture. I watched the suspects throw it out by the wayside. I hope you can figure out what it means and maybe find their stash.

Important detail: Once you find the cache, you are looking for the information to open the container. The required information is not on this page and can only be gained once you find the cache. More puzzling may be required to open the container. Once opened, you may find some more useful information inside the logbook.
