Brinnen replied with a question.
"Can you communicate with Mr. Harvey Grimm?"
Aaron shook his head.
"I do not even know where he does his work. Forgive me for reminding you," he added, "that your sister is in great distress."
The young man stepped into a taxi.
"It is necessary that I see Harvey Grimm as soon as possible," he insisted.
"Harvey Grimm won't be hurried over his work," Aaron declared. "For your own sake he is better out of sight until it is concluded. Shall I tell the man to go to the Milan?"
Brinnen nodded. He leaned out of the window for a moment, however, before the cab started.
"Mr. Aaron Rodd," he said, "do you mind if I speak to you for a moment with perfect frankness?"
"Not in the least," Aaron assured him promptly.
