An attorney for the authors told the court that Brown's wife, Blythe Brown, and Planton scoured religious and historical texts on Brown's behalf as he wrote his novel, typing up notes and in some instances, copying parts of the 1982 book.
Planton said he doesn't know anything about that.
"His wife was doing much of the research," said Planton, who said he didn't save any of his e-mails. "They work in a very symbiotic relationship."
