Kitabkhana commented a while back that perhaps the coincidences between Dan Brown's The Da Vinci Code and Lewis Perdue's Daughter of God weren't striking enough to prove that Brown was a plagiarist.

Dan Brown has denied reading Perdue's book, let alone copying from it, and the case is as complex as you'd expect when it's an issue of plot rather than line-by-line copying involved. Lewis Perdue writes in to Kitabkhana: "The similarities are more extensive than most think. Like many things in life, things by themselves don't tell the truth they do when viewed in context." Here's an article from the Chicago Sun-Times, and here's a link from Perdue's website. The fight's spilled over to Amazon's pages: on Dan Brown's Da Vinci page, 14 readers currently recommend Daughter of God instead of the Da Vinci Code. The Babu notes that many readers have pointed out spelling errors and errors of historical fact in the Code; it would be interesting to see whether the same errors show up in Daughter of God.
