I did not relish the idea of playing the spy, but I was breaking no confidence, and, after all, it was necessary to protect one's own friends. My plan was soon formed. I walked along the narrow street, waited five minutes at the farther end, and returned cautiously to a dingy cabaret, from which a good view of the house could be obtained.

"Now," thought I, "unless my wits are wool-gathering, I am about to behold a miracle. I am going to see two men leave a place which they did not enter. Surely this Martin is something more than an astrologer?"

For nearly an hour I remained with my eyes fixed on the door, which, however, remained closed, and I began to feel a trifle discouraged. What if I had discovered a mare's nest? The important letter was still in my pocket, and Mazarin would be none too pleased at the delay. Perhaps it would be best to abandon the enterprise and to return at once.

I had almost resolved on this plan when two men strolled past the inn. Filled with amazement, I rose quickly, and went into the street. The door of the astrologer's house was shut; in truth it had not been opened, yet here were my mysterious strangers several yards in front of me! Rubbing my eyes, I wondered if I had made a second blunder! But that was impossible, and the idea not worth considering. While I stood thus, dazed and half-stupefied by the strangeness of the affair, the men had walked half-way along the street.

Paris was now fully awake, the shops were open, people were hurrying to their daily tasks, and the number of persons abroad made it difficult to keep sight of my quarry. Several times the men stopped, and glanced behind, as if afraid of being followed, but they did not notice me, and, after a long roundabout journey, we all reached the Rue St. Dominique.

Here the strangers, evidently concluding that caution was no longer necessary, pushed back their hats and drew their cloaks from their faces. It was as I had suspected from the first—the tall man was my cousin Henri, but his companion was unknown to me. Taking a good look, in order to describe him to Mazarin, I found him to be a short, dark man, with an ugly face, but beautiful white teeth. His eyes were beady and restless, he was bandy-legged, and walked with a peculiarly awkward gait.

Half-way along the street the two stopped outside a handsome building, conversed earnestly together for several minutes, and then, ascending the steps, disappeared.

"Pouf!" I exclaimed. "What can that little bandy-legged fellow be doing at the Hotel de Chevreuse? I wager he and my cousin are brewing some fresh mischief."

As no good could possibly come from further waiting, I turned away, and hurried back to the Palais Royal, eager to inform Mazarin of my discovery, and to get my breakfast. Roland Belloc met me in the courtyard, and held up a warning finger.

"You are in disgrace, my friend," said he, gravely; "the Cardinal has been waiting for you a long time. He has sent out repeatedly in the last hour to ask if you had returned."
