A New Zealand historian and his co-author who claimed the The Da Vinci Code writer Dan Brown plagiarised their book have lost their case.
A British court has rejected claims by Michael Baigent and Richard Leigh that Brown stole ideas from their book The Holy Blood and the Holy Grail.
Both books centre on the idea that Jesus Christ married Mary Magdalene and had children, whose bloodline survives to this day.
But the judge backed Brown's contention that while he had read the earlier book, it had been just one of many influences.
