Over the next several days, or weeks, Dave plans to put on a demonstration of his investigative process. If you have followed Dave's work, you already know that he is one of the greatest investigators of the past few centuries, equaled only by legends like Sherlock Holmes and Lieutenant Columbo.
Dave started his current investigation in the position you see below. This is a great position for an investigation, because it offers Dave a great view of the room, but he is also close enough to the ground to quickly launch himself towards anything unusual. It is good to be flexible.
Now Dave is beginning to peruse the various areas where he might find a clue. "A clue to what?" you might ask. But to Dave, that doesn't matter. He just wants to know about anything fishy going on around his home. At this phase, the investigation is more of a general investigation. If something fishy turns up, it will become more targeted.
You can see that Dave's first order of business is to check his blind spots. He wants to make sure he won't be attacked by something hiding out in the box. He already checked the higher levels of his cat-tree before assuming his position, so he knew nothing could attack him from above. And now has assured himself that nothing is in the box. Stay tuned for more on Dave's investigative process.
