“To receive your report,” came the quiet reply. “I take it that you followed my instructions.”

“I did,” said Mann quietly. He had regained his composure after the first surprise. “But I must confess that I am completely in the dark.”

“That may all be true,” came the whispered voice. “But let us be specific. What are your opinions in regard to the Caulkins murder?”
