LONDON, England (Reuters) -- Author Dan Brown appeared in court on Monday at the start of a trial in which two historians say he copied their work to write "The Da Vinci Code" best-seller and are suing his British publisher.
Richard Leigh and Michael Baigent are suing their own publisher Random House for lifting "the whole architecture" of the research that went into their 1982 non-fiction book "The Holy Blood, and the Holy Grail," itself a bestseller.
