She laughed. “That is true. I haven’t, have I?” Serious again, she went on. “He seems worried. Something seems to follow him about—some thought, some apprehension, some worry.”

“I told him,” she said, “that we—”

She stopped there, too, and looked at me.

But this time he had hardly had time to go down the steps before I heard his key in the door again and the feet of ‘Laddie’ on the hall floor. I ran out to ask if he had forgotten anything, and it was a dreadful shock to me.”
