Carl's careless air of interest altered indefinably. Inspecting his chafing prisoner now with narrowed, speculative eyes which glinted keenly, he fell presently to whistling softly, laughed and with tantalizing abruptness fell silent again. Immobile and subtle now as his silent companion, he stared curiously at the other's fastidiously pointed beard, at the dark eyes and tightly compressed lips, and impudently proffered his cigarettes. They were impatiently declined.

"Monsieur is pleased," said Carl easily, "to reveal many marked peculiarities of manner, owing to the unbalancing fact, I take it, that his mind is relentlessly pursuing one channel. Monsieur," went on Carl, lazily lighting his own cigarette and staring into his companion's face with a look of level-eyed interest, "Monsieur has been praying ardently for—opportunities, is it not so? 'I will humor this mad fool who motors about in the rain like an operatic comet!' says Monsieur inwardly, 'for I am, of course, a stranger to him. Then, without arousing undue interest, I may presently escape into the storm whence I came—er—driving atrociously.'"

The man stared.

"Monsieur," purred Carl audaciously, "is doubtless more interested in—let us say—camp fires for instance, than such a vulgar blaze as yonder car."

"One is powerless," returned the other haughtily, "to answer riddles."

Carl bowed with curiously graceful insolence.

"As if one could even hope to break such splendid nerve as that!" he murmured appreciatively. "It is an impassiveness that comes only with training. Monsieur," he added imperturbably, "I have had the pleasure—of seeing you before."

"It is possible!" shrugged the other politely.

"Under strikingly different conditions!" pursued Carl reminiscently. There was a disappointing lack of interest in the other's face.

"Even that is possible," assented the foreigner stiffly, "Environment is a shifting circumstance of many colors. The honor of your acquaintance, however, I fear is not mine."
