“In the next box to yours.”

“The m-man in the black d-domino? Then—then it was you who trod on my g-gown?”

“You see, I had to contrive that you should be out of the way for a few moments,” he apologized.

“Yes, of course,” nodded Horatia, quite appreciating this. “It was very c-clever of you, I think. And when I c-came back and thought your voice odd— that was you?”

“It was. I flatter myself I imitated Lethbridge’s manner rather well. I admit that the noise those fiddles made helped me.”

She was frowning again. “Yes, b-but I don’t understand quite. D-did Robert exchange d-dominoes with you?”

A laugh lurked in his eyes. “It was not precisely an exchange. I—er—took his, and hid my own under a chair.”
