Suspense is building in the "The Da Vinci Code" trial in London.
A judge is expected to rule this morning on whether novelist Dan Brown's publisher is guilty of copyright infringement.
Two authors say ideas in their book were stolen and appear in the blockbuster novel "The Da Vinci Code."
The books explore theories that Jesus married Mary Magdalene, fathered a child and that the bloodline survives.
Most historians and theologians scoff at the idea.
A victory by the plaintiffs would stun the world of copyright law because it would challenge the concept that copyright protects the expression of an idea rather than the idea itself.
A plaintiff victory also could hold up next month's release of the movie, though Sony Pictures says that's not the case.
