“Oho, my uncle,” thought Wilfrid, who had observed this little by-play, “why did you give a written message, when an oral one would have sufficed? There is something on that card you do not wish me to see. Very good! Forewarned is forearmed.”

After a brief interval there came a tapping at the door.

“Wait a moment, Williams,” cried Lord St. Helens. “Stay outside till I call.”

“Williams? Why, I thought it was Mulgrave you sent for?” said Wilfrid in mock surprise.

“I am to take it, then, that you have quite made up your mind to fight this duel?”

“Certainly.”

“Well, I have made up my mind that you shall not.”
