"Our friend is unusually attentive," said the earl, with a glance at the pitcher.

"Yes; perhaps we have misjudged him."

"Perhaps, but I am not sure. Scott, will you hold the candle?"

He took the pitcher and peered into it attentively, rather to Scott's surprise. Then he poured out a small quantity, and tasted it.

"I hope you will excuse me from drinking, Mr. Grant," said Scott. "I promised my father I would never drink whisky."

"Even if you did indulge, I should not advise you to drink any of this."

"Why not? Is it of poor quality?"

"I am quite confident that it is drugged. It has a peculiar taste, and I detect minute particles of some foreign substance which has been mixed with it."

"Poison?" asked Scott, looking startled.
