"Of course. After you are done with it?"
"Hah! He will not say until he has a specimen. When can you have some ready?"
"Now. This minute. Will you take it away with you?"

"Nothing particular."
"Can you come to my place between twelve and half past?"
"Certainly."
"Without fail?"
"I'll be there to the minute you say."
"Very well. Let it be twelve exactly. I have a most excellent reason of my own for punctuality. Bring some of the alloy with you. Knock at the door once, one knock, the door in Chetwynd Street, mind. I'll open the door for you myself. Mind, not a word to a soul, and above all don't go into the Hanover hard by. I have reasons for this--most important reasons."
