"We must act at once!" he exclaimed, and pulled the telephone toward him.

"But not with too great haste, General," protested Chester, also rising.
"We must first decide upon a plan."

"What do you mean?" asked the general.

"Why," said Chester, "if we hope to capture Duval—who will be on hand to-morrow, and who is likely to shoot the President himself—we must figure out the best means of doing so."

"I shall have the President cancel his engagement."

"That," said Chester, "might only delay the assassination."

"What would you suggest?"

Chester was silent for some minutes before he replied:

"If the President doesn't make his address to-morrow, his life probably will be attempted the next day or the next. If he does speak, Duval is sure to be on hand. Jean and I must be in the crowd, so that Duval may see us; for, if we are not there, Duval may suspect treachery and shoot the President himself.

"Seeing us there, however, Duval will take no action himself. As the President's speech progresses, Duval will be waiting for me to fire. He will be continually thinking that I will do so in another moment.
