The Man in Lower Ten by Mary Roberts Rinehart

The surprising change in her held me speechless. All the animation of the breakfast table was gone: there was no hint of the response with which, before, she had met my nonsensical sallies. She stood there, white-lipped, unsmiling, staring down the dusty road. One hand was clenched tight over some small object. Her eyes dropped to it from the distant road, and then closed, with a quick, indrawn breath. Her color came back slowly. Whatever had caused the change, she said nothing. She was anxious to leave at once, almost impatient over my deliberate masculine way of getting my things together. Afterward I recalled that I had wanted to explore the barn for a horse and some sort of a vehicle to take us to the trolley, and that she had refused to allow me to look. I remembered many things later that might have helped me, and did not. At the time, I was only completely bewildered. Save the wreck, the responsibility for which lay between Providence and the engineer of the second section, all the events of that strange morning were logically connected; they came from one cause, and tended unerringly to one end. But the cause was buried, the end not yet in view.

Not until we had left the house well behind did the girl's face relax its tense lines. I was watching her more closely than I had realized, for when we had gone a little way along the road she turned to me almost petulantly. "Please don't stare so at me," she said, to my sudden confusion. "I know the hat is dreadful. Green always makes me look ghastly."
