New Book on 'Secret Mark'

Maybe this is old news to the rest of the world but I was just flipping through Edward R Smith's the Temple Sleep of the Rich Young Ruler (2011 Steiner Books).  I notice that Scott Brown is mentioned in the acknowledgments. The book cites extensively from Alan Pantuck's research.  It is a vigorous defense of the authenticity of the document.  When things slow down I will have to read this book.
