your head."

"It is. Did you ask Mr. Scott the name of the man with whom he dined
last evening."

"Yes."

"It was----"

"Alvarez Lazaro."

"I thought it!"

"Why, how did you know any----"

"The white-haired man you met here is Alvarez Lazaro."

"No?"

"And this Lazaro has boldly informed me that he was once the bosom
friend of Porfias del Norte and is now his avenger."

"What's that?" gasped Hatch. "Why, what does he propose to do?"

"He has threatened all sorts of things. Look out for him, Mr. Hatch. So
he dined with Mr. Scott, did he? And Mr. Scott was taken ill at the
Waldorf! Mr. Hatch, when I leave here I shall call on Mr. Scott's
physician and have a talk with him. My suspicions are thoroughly
aroused."

"You don't suspect foul play, do you?"

"As I have said, my suspicions are thoroughly aroused. This whole affair
is queer."

At this moment the chauffeur uttered an exclamation of satisfaction,
backed from beneath the machine, wrench in hand, and announced that the
breakdown was remedied at last.

Frank remained until the machine was ready to start and Warren Hatch had
stepped into it. Mr. Hatch waved his hand and was soon lost to view down

Then he spoke, and, if possible, his voice terrified me even more than
his eyes, for it was the voice of your bitterest enemy, Porfias del
Norte. Of course, I know Del Norte is dead, Frank; but this man alarms
me all the more because of that."

"What did he say to you?"

"He begged my pardon and said he had not meant to alarm me. He was very
courteous, just the same as Del Norte. Can he be a relative of your
enemy?"

"I don't think so, Inza. Where is he now?"

"He left at once by the door on the opposite side."

"I'd like to see him a moment," said Merriwell grimly.

"Keep away from him, Frank!" implored Inza, grasping his arm. "I don't
understand it, but I have a feeling that he will bring some trouble to
us."

It was not an easy matter to fully reassure her, bu
