I glanced in the direction indicated, and although I saw nothing of the Commissaire, I slipped back willingly enough through the lifted curtain into the deserted room behind. It was evidently an office of some kind, for it contained only a desk and some chairs, and 55 was unlighted, except for the gleam from between the curtains. The outer wall was so thick a considerable space separated the room from the window, which was screened off by heavy drapery. De Artigny appeared familiar with these details, for, with scarcely a glance about, he led me into this recess, where we stood concealed. Lights from below illumined our faces, and revealed an open window looking down on the court. My companion glanced out at the scene beneath, and his eyes and lips smiled as he turned again and faced me.

“But, Monsieur,” I questioned puzzled, “why was it not easy? You met with trouble?”

“Hardly that; a mere annoyance. I may only suspect the cause, but an hour after I left you my ticket of invitation was withdrawn.”

“Withdrawn? by whom?”

“The order of La Barre, no doubt; an officer of his guard called on me to say he preferred my absence.”

“’Twas the work of Cassion.”

“So I chose to believe, especially as he sent me word later to remain at the boats, and have them in readiness for departure at any minute. Some inkling of our meeting must have reached his ears.”

“But how came you here, then?”

He laughed in careless good humor.

“Why that was no trick! Think you I am one to 56 disappoint because of so small an obstacle? As the door was refused me I sought other entrance and found it here.” He pointed through the open window. “It was not a difficult passage, but I had to wait the withdrawal of the guards below, which caused my late arrival. Yet this was compensated for by discovering you so quickly. My only fear was encountering someone I knew while seeking you on the floor.”
