Bruce Bingham Cassiday, writer and editor. "Bruce Cassiday was a multi-talented producer of popular fiction, hard-boiled suspense and espionage tales, carefully crafted Gothics (a literary sub-genre that needs a firm hand on its inevitably Byzantine plots), medical melodramas and television novelisations, as well as "How to" tomes on lawns and landscaping, home carpentry, solar houses, dieting, and a number of ghosted biographies (only a few of which he owned up to)."

There's not much biographical material out there on Dinah Shore. That's pretty remarkable, so Bruce Cassiday's work stands as the most comprehensive book available. His writing isn't supported by source material, so it's not particularly helpful in tracking down original citations. He doesn't acknowledge any interviews or support.
Shore was a wildly popular American entertainer whose life story deserves to be told in modern terms or in any fashion, beyond this one book. Cassiday's writing seems intended for 1979's mass-market women's market. That mere fact however, helps put the book's subject and style into context. I read this as research for my podcast, Advanced TV Herstory.
