You've waited, you've wondered, but now it's here. Top Shelf is back. This week, David Pierce takes a look at the world of private investigating. What kind of gear will he need? Where does he park his unmarked van? How many fake mustaches should he own? It turns out it's a bit more complicated than he originally thought.

This summer, Top Shelf is back and better than ever. We're taking deep looks at the technology we see and don't see, the technology we watch and the technology that watches us. The way we eat and drink, the way we play, the way we work, the way we get around — it's different today than it was yesterday, and it's probably going to change again tomorrow. We'll be here, working through what it all means, and figuring out what's next.
