Diagnosis Murder — John Holt

“Mr. Kendall, in the past few months there have been a number of doctors who have mysteriously disappeared, or whose deaths were either alleged to be accidents, or were suicides, or they were actually murdered.” Kendall made a mental note to find out about these ‘other doctors.' “A number of doctors you said. How many are we talking about?” Mrs. Eaton thought for a few moments. “To my knowledge there have been at least eight cases in the past six months. There may be a whole lot more that I know nothing about.”
