““Another bad cure is the sentence awkwardly stretched out by a "that" or "which" clause. For example, "Leaping from the couch he seized the revolver from the bookshelf that stood behind the armchair," or, "She turned, shrieking, throwing up her arms in terror at the sight of the gorilla that had arrive that morning from Africa, which had formerly been its home." What happens in such sentences, obviously, is that they tend to trail off, lose energy.””
