All the sullen restraint fell away from her and she was electric in the violence of her protest.
"Arrest him! That wonderful man! Arrest me? You dare not! You dare not!"
"I shall dare do lots of things unless you tell me what I want to know."
"What do you want to know?" she demanded defiantly.
"I want to know the most likely address at which your friend the doctor can be found—the fact is, Miss Glaum, the game is up—we know all about the Green Rust."
She stepped back, her hand raised to her mouth.
"The—the Green Rust!" she gasped. "What do you mean?"
"I mean that I have every reason to believe that Doctor van Heerden is engaged in a conspiracy against this State. He has disappeared, but is still in London. I want to take him quietly—without fuss."
Her eyes were fixed on his. He saw doubt, rage, a hint of fear and finally a steady light of resolution shining. When she spoke her voice was calm.
"Very good. I will take you to the place," she said.
