THE HIGH CHAPARRAL 315: The Journal of Death (1/9/1970)
A former prison doctor accused of malpractice becomes the only man to whom John Cannon can appeal in efforts to save the life of his seriously ill wife. Lawman Tad Garnet requests a night's lodging at the Cannon ranch while escorting Mathew Kendel, a one-time prison physician, to jail on charges of willfully causing the deaths of many of his convict patients. When Victoria suddenly falls ill and needs an operation to save her life, John must ask the now-embittered Kendel for help.
