It's Garret Graff's Watergate, A New History
He does a good job of tying a lot of things together. Not only the break-in and aftermath, but things like the "Chennault Affair", his paranoia over the Pentagon Papers, GEMSTONE, etc. Not to mention explaining some of Felt's motives as Deep Throat (It was as much an effort to undermine Patrick Grey as much as anything else)
I find it interesting in light of what is currently happening. Especially if you look at it in the time of Trump...
