Max thrilled. 'The search for the idea! How splendid! Where must it begin? Not in fashionable Paris! Oh, not in fashionable Paris!'

"Fashionable Paris!" The Irishman laughed in loud disdain. "Oh no! For us it must be the highways and the byways, eh?"

Max freed his arm. "Ah yes! that is what I want—that is what I want. The highways and the byways. It is necessary that I am very solitary here in Paris. Quite unknown, you understand?—quite unnoticed."

"The mystery? I understand. And now, tell me, shall it be the highways or the byways—Montmartre or the Quartier Latin?"

Max smiled decisively. "Montmartre."

"You know Montmartre?"

"No."

The Irishman laughed again. "Good!" he cried. "You're a fine adventurer! You have the right spirit! Always know your own mind, whatever else you're ignorant about! But I ought to tell you that Montmartre swarms with your needy fellow-countrymen."

The boy looked up. "My needy fellow-countrymen will not harm me—or know me."

"Good again! Then the coast is clear! I only thought to warn you."
