Query: Not What I Expected

As a big Perry Mason fan, I have been looking for a bio of Raymond Burr for a while. This, unfortunately, is the only one that has, to date, been written. While it does a fairly good job of detailing the many areas in which Burr worked (from the theater to radio to orchid farming...yes, orchid farming), it does little to tell us about the actual man. The ending falls flat. Little is given on how Burr dies, just one brief paragraph that he does as the book closes. Burr's main piece of work, the "Perry Mason" series, is given little play. No insight whatsoever into why the series came about, how it developed, etc. This book, while semi-interesting reading, leaves me wanting more. Will someone please write a bio on Mr. Burr???
