As a writer, I hate to leave negative reviews, but Brian McFadden leaves little choice. Starting with the positives, however, if you're a Perry Mason fan or a Raymond Burr fan, then you will probably learn some tidbits about both subjects, and the book is well-illustrated with a nice collection of photographs.
McFadden wrote this book in 2016 based on his notes from a couple of interviews (I suspect one interview) that he did with Raymond Burr in 1985. It's part biography of Burr, part history of the show, part memoir of how Perry Mason reminds McFadden of the good old days when he was a kid. It reads as if it was thrown together in a hurry in an effort to make a quick buck off the name "Perry Mason."
