"I am to go to your house?"
"Yes."
"When?"
"Any time you may elect."
"And then?"
"I will conceal you. You can see the men who come to talk with my brother. You can overhear all that passes. You can identify them and shadow them. I think they go from our house to the secret workshop."
"I will arrange with you to go to your home."
"When?"
"At some future time."
"Very soon?"
