“Well, think fast.”

She turned to Karr. “Your first name is Elston, isn’t it?”

“Yes.”

She said, “I have a haunting memory in the back of my mind that Karr’s first name was Elston. I can’t remember. Perhaps it’s just the association of ideas, having met Mr. Elston Karr this afternoon. I... I may have confused his first name.”

“With what?”

“With the name of my father’s partner.”

“What other Karrs do you know?”

“None who spell their names this way.”

Tragg looked up at Karr. “Well?” he asked.

Karr said, “In the fall of 1920 and the spring of 1921 I was in partnership with three men in Shanghai. One of them was named Dow Tucker. I think he’s this girl’s father. The other one was a man named Hocksley.”
