"Come in," said Boundary, thinking it was the landlady.
He was in the middle of the room as he spoke, and he went back step by step as the visitor entered. His tongue clave to the roof of his mouth, his eyes were starting out of his head.
"You! You!" he croaked.
"Little Jack o' Judgment," said the mask mockingly. "Poor old Jack! Come to take farewell of the colonel before he goes to foreign parts!"
"Stop!" cried Boundary hoarsely. "I know you, damn you! I know you!"
He pulled back the curtains and glared out of the window. There was no need to ask any further questions. The house was surrounded. He swung round again at his tormentor and faced the white mask in a blind fury of rage.
"You're clever, aren't you?" he said. "Cleverer than all the police! But you weren't clever enough to save your son from death!"
The masked figure reeled back.
"Ah, that's got you! Little Jack o' Judgment!" mocked the colonel. "That's got you where it hurts you most, hasn't it? Your only son, too! And he went to the devil all the faster because of me—me—me!" He struck his breast with his clenched fist. "You can't bring him back to life, can you? That's one I've got against you."
