Martin Mayer has been writing about banking for decades. He has held positions in government, and testified as an expert in various governmental committees. He has known personally many of the people about whom he is writing in this book.His writing style is dense. He often assumes the reader is familiar with banking terms or processes (or can go look them up). If you can get through this, the information he provides is priceless. I came away from reading this book with a variety of insights into banking and the federal reserve that will continue to inform me for years to come. I have read a number of books on the fed, and this is certainly one of the best (along with Greiders).
