Mr. Pottermack's Oversight by R. Austin Freeman

On each of the two men who parted at the gate the brief interview produced its appropriate effects; in each it generated a certain train of thought which, later, manifested itself in certain actions. In Mr. Pottermack, as he softly reopened the gate to listen to the retreating footsteps, once even venturing to peep out at the tall figure that was striding away up the path, the encounter was productive of a dim uneasiness, a slight disturbance of the sense of security that had been growing on him since the night of the tragedy. For the first few days thereafter he had been on wires. All seemed to be going well, but he was constantly haunted by that ever-recurring question, "Was there anything vital that he had overlooked?"

The mysterious photographer, too, had been a disturbing element, occasioning anxious speculations on the motive or purpose of his inexplicable proceedings and on the possibility of something being brought to light by the photographs that was beyond the scope of human vision. But as the days had passed with no whisper of suspicion, as the local excitement died down and the incident faded into oblivion, his fears subsided, and by degrees he settled down into a feeling of comfortable security.
