Pierre lifted the latch and we passed through a wall some sixteen feet thick and into a stone-paved courtyard with a broad flight of steps at its farther end sweeping to the top of the circular defence. Flanking the sunken courtyard itself were a dozen low vaultlike compartments, some of them sealed by heavy doors. At one of these, containing a narrow window, Pierre knocked. The door opened and I stood in the presence of the Brigadier Bompard.

"The American gentleman," announced Pierre, relieving me of my gun.

The brigadier bowed, looked me over sharply, and bade me enter.

"At your service, monsieur," he said coldly, waving his big freckled hand toward a chair drawn up to a fat little stove blushing under a forced draft.

"At yours, monsieur," I returned, bowed, and took my seat.

Then there ensued a dead silence, Pierre standing rigid behind my chair, the brigadier reseated back of a desk littered with official papers.

For some moments he sat writing, his savage gray eyes scanning the page, the ends of his ferocious moustache twitching nervously as his pen scratched on. Back of his heavy shoulders ran a shelf supporting a row of musty ledgers, and above a stout chest in one corner was a rack of gleaming carbines.

The silence became embarrassing. Still the pen scratched on. Was he writing my death-warrant, I wondered nervously, or only a milder order for my arrest? It was a relief when he finally sifted a spoonful of fine blue sand over the document, poured the remaining grains back into their receptacle, puffed out his coarse red jowls, emitted a grunt of approval, and raised his keen eyes to mine.

"A thousand pardons, monsieur," I began, "for being where I assure you I would not have been had I known exactly where I was."
