“Doctor Plaxico,” said Burk, “do you know what is the matter with Mrs. Demar?”

“No.”

“Have you no suspicions?”

“Yes.”

“Have you any objections to telling me what you suspect?”

“Yes.”

“Why?”

“Because it would do no good, and might do much harm.”

“Would you be surprised if I were to guess exactly what you suspect?”

“Indeed, I would.”
