"I'm sorry for bothering you, Mister Warrington. I'll just be going now," she said in a rush before take a few more hurried steps backward. Because she wasn't paying attention to where she was going, though, her shoe caught on a slightly lifted stone in the path, and she stumbled back, landing hard on her arse. Moisture sprung to her eyes, and she let out a mild curse.
