A guilty pride thrilled the depraved boy's heart to feel that he, alone, in all the crowded ward, knew what manner of human devil lurked behind those innocent-looking blue spectacles.

He had seen the ferocious grin which relaxed Fritz Braun's bearded lips into a cruel grin, as the sly lad made a gesture which indicated tidings of great joy. Einstein's dress and bearing was fully worthy of his respectable business station. He might well be taken for the precious "only son" of some well-to-do Jewish-American merchant.

Quick to learn, he had aped the mien of his American fellow employees, and his "educational evenings" at the "Irving Place," the "Thalia," and the "Germania" had given to his bearing what he fondly deemed an "irresistible social swing."

Greedy of pleasures, gluttonous and covetous, the young Ishmael ardently looked forward to a comfortable ill-gotten revenue at the hands of the man, who—through a skilful manipulation of the German janitor of the Western Trading Company's office—had obtained the place of office boy, "with substantial references," for the son of his cast-off paramour.

Leah Einstein had long forgotten the face of the reckless Polish country noble who was the real father of this budding criminal, and the lad himself but dimly discerned the drift of his Mephistophelian patron's proposed villainy.

Timid and cowardly at heart, the young waif would have shuddered had he known of the callous-handed and desperate murders which had shocked Vienna just before Hugo Landor, a talented and handsome young chemist, disappeared forever in flight, lost under a cloud of scandal caused by drink and a maddening devotion to a baby-faced devil of the Ring Strasse Theater chorus, a woman at whose feet the hungry-eyed aristocrats had knelt to sue, a man-eater, a hard-hearted, velvet-eyed, reckless and defiant devil.

At an almost imperceptible nod Einstein drew near to his patron, taking the vacant place in the little alcove, à deux, with his back prudently screening him from any chance visitor who might know the Western Trading Company's personnel. Braun was eager for his spy's report now.

"All right, at last!" the youth huskily whispered. "I watched him meet her, at the picture window, you know. I had posted her! And then he slyly followed her over here and went three blocks out of his way to pipe her off here! So, after his lunch at Taylor's, I put her again onto his homeward way! And he's caught on! No matter! She will tell you the rest herself!"

When the eager lad had finished, Fritz Braun growled under his breath, "You are sure you made no bungle?"

"Dead sure," gaily answered the boy, draining his bock of Muenchner, "I followed him to the bank and to Taylor's, and he is unsuspecting of any plant, I know."
