“Prince,” he said, “there can be no question about that. I thank you very much for it, but I must decline.”

“Under certain conditions,” the Prince continued, “I should have imagined that the climate here might prove most unhealthy for you. You must remember that I was a witness of your slight indisposition the other day.”

“In my profession, sir,” the detective said, “we must take our risks.”

The Prince came to a standstill. They were at the parting of the ways.

“I am very sorry,” he said simply. “It was a great post, and it was one which you would have filled well. It is not for me, however, to press the matter.”

“It would make no difference, sir,” the detective answered.
