He smiled slightly and picked up his flute. With infinite softness a waltz danced lightly through the quiet room. To such a fanciful, eerie piping might the ghost of a child have danced. Then without pause or warning it swung dramatically into a stirring melody of power and dignity. The wretched man by the table buried his face in his hands and groaned. "Ah!" said Carl softly. "So Monsieur has heard that tune before? That in itself is illuminating." With a leer Hunch entered and deposited a tray upon the table. Carl poured himself some whiskey and pushed the decanter toward his guest with a significant glance. Jokai of Vienna poured and drank with a shudder of nausea. "We've a new chessboard," said Carl. "It's most ingenious. Hunch spent a large part of his valuable morning shopping for it. The board and chessmen are metal and I myself have added one or two unique improvements. Help yourself to some more whiskey--do." "Monsieur," faltered Jokai desperately, "I--I can not." "Hunch," said Carl softly. "His Nibs won't drink." Instantly from the wired metal points of Jokai's chair a stinging electric current swept fiendishly through his body. Last night it had goaded him unspeakably. To-night, with every tortured nerve leaping, it was unbearable. Shaking, he poured again and drank--great drops of sweat starting out upon his forehead. Where the rope bound his ankles the flesh was aching dully. "Mercy!" he choked. "I--I can not bear it." "There is a way to stop it!" reminded Carl curtly. "The ivory chessmen for me, Hunch. And whenever he refuses to drink--start the current." With the metal chessboard before him, Carl idly arranged his ivory men. Jokai touched a metal pawn and shuddered violently. The metal board was wired. Thenceforth every move in the game he must play with the metal men would complete the circuit and send the biting needles through his frame. It was delicately gauged, a nerve-racking discomfort without definite pain, a thing to snap the dreadful tension of a man's endurance at the end. "Ah! Monsieur!" cried Jokai wildly. "It is inconceivable--" "Play!" said Carl briefly. White and grim his guest obeyed. In terrible silence they played the game through to the end. "Let me pour you some more whiskey," insisted Carl with infernal courtesy. "Let us understand each other. Whenever I drink, I expect you to do the same. As for you, Hunch, you'll kindly stay sober!" Jokai gulped the nauseating torture to the end. He was faint and sick. By the end of the third game, every move had become convulsive. The insidious bite of the current was getting horribly on his nerves. Still with desperate will he played on. Drunk and dizzy--his veins hot and pounding, he stared in fascinated horror at the face of his merciless opponent. Through the film of smoke it loomed vividly dark, impudent, ironic, the mobile mouth edged satirically with a slight smile. "Are you man or devil?" he whispered.
