"I'm no knocker, I'm a booster. Besides I don't believe in signs," was the surprising response.

The visitor faced about as he spoke, and Martin took stock of him. He was a hunchback. He was seedily clad in a shiny black suit, but a modish green velvet hat, several sizes too small, perched precariously atop his very large head and gave him an oddly rakish appearance. But his face was pleasing—a wide grin, a snub nose, a pair of twinkling eyes beneath a broad, intelligent forehead. Martin immediately commenced to thaw as the other smiled.

The hunchback carried a book under one arm, a formidable appearing volume. With a dexterous flirt, he bounced it into his hand and thrust it beneath Martin's very nose.

"The bargain of the century—cannot afford to miss it—wonderful opportunity first time offered," he began in a sing-song.

Martin stiffened with surprise. Not at the words; he was accustomed to book-agents of strange guise. But the voice! A rich, throaty tenor with not a squeak in it. The man's discourse was like a song.

But surely, such a bronzed and weather-lined coating as this man's face wore was never gained by winning past janitors or tramping city streets.

"Possible to make offer only because of great advertising campaign—you reap advantage free of charge. Wonderful volume absolutely free. You merely subscribe to Coleman's Weekly—ten cents a week, fifty cents a month, price of magazine—wonderful Compendium of Universal Knowledge—cost you absolutely nothing——"

The hunchback pattered on. Book-agent or no, Martin conceded he had the technique of the craft at his tongue's tip. His eyes—suddenly, Martin was aware of the peculiar behavior of the other's eyes. The were roving about the office from point to point, as if the fellow were endeavoring to fix in his mind every feature of the room. But most often, Martin noticed, his gaze rested upon the door to Smatt's private office, through which came at intervals the hoarse murmur of Smatt's voice. Once, atop the murmur, came a few words in Dr. Ichi's clipped and even tones——
