"Quick work," the journalist congratulated him sarcastically. "The assignment is only a little over two months old."
"Well, I might have guessed, any time in those two months, but I wanted to make certain."
"Are you certain?"
"Reasonably."
"What is it?"
"Typhus."
"What's that? Something like typhoid?"
"It bears about the same relation to typhoid," said the Doctor, eyeing the other with solemnity, "as housemaid's knee does to sunstroke."
"Well, don't get funny with me. I don't appreciate it. Is it very serious?"
"Not more so than cholera," answered the Doctor gravely.
