Doyle Jeffries is a character who appears in Fantasy Flight Games' Arkham Horror Files line of Cthulhu Mythos-related games and fiction. He is the editor of The Arkham Advertiser, Arkham's local newspaper.
Professor Norman Withers approached Jeffries at the offices of the Advertiser requesting access to their archives in an effort to find others which had suffered the same fate as his friend Claus Schmidt, who had been abducted by a Hound of Tindalos. Jeffries obliged this request, on the condition that Withers later give him an exclusive interview on the event. Jeffries did indeed get his exclusive, but it was a heavily-edited version of the tale which featured no unnatural events.
