I recently re-read Frank Peretti's thriller The Oath, and I couldn't help but notice parallels to Lovecraft's The Shadow Over Innsmouth. Both stories involve dark secrets kept by isolated communities who've made a pact with evil. The residents in both tales dislike nosy outsiders and refuse to speak to them. There have been many disappearances of locals and outsiders over the years in both novels. Old diaries and letters provide important sources of information in each. I don't think Peritti necessarily copied Lovecraft, but both authors used similar ingredients to create suspense. And I think The Oath would make an interesting CoC campaign.
Anyone else read it? What do you think?
