"Monsieur le Chevaliér—Follow without fear the man who brings this note, he is deputed by me to lead you to the house where the Duc d'Olivares and Captain la Jonquiere await you."
"Stay," said he, giving him the note, "if any one comes in my name, he will give you a similar letter."
"Is that enough?"
"One cannot be too careful; besides the letter, he will show you the half-coin, and at the door of the house to which he leads you, ask for the third sign."
"Which will be."
