"Very well, then," said Speed, "that is agreed; we will look you up in a week from now."
"I should be pained," said Lecocq, "to put you to that trouble. As soon as I get the report from my men I will communicate with you and let you know the result. In a few days I shall give you the name of the assassin."
"Good-bye, then, until I see you again," answered Speed; and with this he and Brenton took their departure.
"He seems to be very sure of himself," said Brenton.
"He will do what he says, you may depend on that."
The week was not yet up when Monsieur Lecocq met John Speed in Chicago.
"By the look of satisfaction on your face," said Mr. Speed, "I imagine you have succeeded in unravelling the mystery."
"Ah," replied the Frenchman; "if I have the appearance of satisfaction, it is indeed misplaced."
