Longreads Members not only support our daily service, but their financial support allows us to go out and find stories and book chapters that aren’t already available on the web. As part of our Longreads Member Drive, we’re excited to share our latest Member Pick with everyone—it’s an excerpt from Duff McDonald’s new book, The Firm, on the history of McKinsey. Thanks to McDonald and Simon & Schuster for sharing it with the Longreads community.

If you like our service, become a Longreads Member today, and help us get to 5,000 Members.
