Most authors, however, employ the trope as a narrative rest stop, an innocuous way to fill space and time; since the bark is hollow, a reader can read anything into it, or nothing at all. Charlaine Harris, queen of the vampire authors, in Dead as a Doornail: "The entire parking lot was empty, except for Jan's car. The glare of the security lights made the shadows deeper. I heard a dog bark way off in the distance." The chief of Scandinavian crime writers, Henning Mankell: "She begins to tell him. The curtain in the kitchen window flutters gently, and a dog barks in the distance" (The Eye of the Leopard). And "genre" books aren't the only guilty category. Take 2666, Robert Bolaño's magnum opus: "The window looked out over the garden, which was still lit. A scent of flowers and wet grass drifted into the room. In the distance he heard a dog bark." For all we know, these dogs are off-camera sound machines set to woof.
Is there a similar trope in academic scholarship and writing, one that is as concrete and noticeable? I can think of certain turns of phrase, transitions and the like, but nothing comparable to "somewhere a dog barked."
