I had forgotten that I had read this book. Which says it all really. I'm a sucker for anything pertaining to the historical Jesus, and have a Goodread bookshelf with that same title. Even so, I can't put 'Holy Blood, Holy Grail' in that genre. Conspiracy-schmiracy shelf is more appropriate.
To be fair, the idea that J.C. was married is historically plausible, that he survived the cross is accepted in the Muslim religion, and that Mary Magdalen arrived in the south of France along with brother Lazarus, Mary of Bethany and Joseph of Aramathea...who had stopped off on his way to the Glastonbury Festival.
The book is like that box of chocs, lots of soft centred yummies that leave you feeling a little sick and bloated.
