Sir Colenso Ridgeon
Ridgeon is a recently knighted doctor who has seemingly developed a cure for tuberculosis. He falls for Jennifer and when given the choice to save her husband, Louis of tuberculosis or Dr. Blenkinsop he chooses the doctor. He desires to marry Jennifer and with Louis out of the way he believes he will win her.
Jennifer Dubedat
Jennifer is a young, beautiful and charming woman who is devoted to her husband, Louis. She seeks out Dr. Ridgeon in order for him to personally cure Louis, but Ridgeon passes him off to Dr. Bonington as he knows that Louis won't survive by being treated by him. Jennifer befriends all of the doctors except for Ridgeon whom she comes to despise for knowingly not treating her husband and thus killing him. She remarries and holds an exhibit of her late-husband's works.
Sir Patrick Cullen
Sir Patrick is a retired physician who, among his colleagues sees through Louis' artistic genius and judges him to be lacking in honor. Yet, Sir Patrick remains on the outside as he doesn't directly treat Louis, he only gives his opinions to Ridgeon. Specifically that Ridgeon must not choose to treat Blenkinsop merely to marry Jennifer after she is widowed.
Sir Ralph Bloomfield Bonington
Bonington is one of the physicians that meets Jennifer and Louis and finds them both utterly charming and delightful. When Ridgeon decides to pass of Louis' care, it is Bonington who gladly accepts the charge to treat his tuberculosis. Ridgeon knows that Bonington doesn't have his knowledge of how to sequentially treat the tuberculosis, thus by Bonington treating Louis, Ridgeon is allowing Louis to die.
Minnie Tinwell
Minnie is a maid at a seaside resort. She is also the legal wife of Louis Dubedat, which she reveals to the doctors upon he and Jennifer's departure from the dinner. She married Louis when both of them were already wed and then after their honeymoon they parted ways until she saw him with the doctors this night.
Dr. Blenkinsop
Blenkinsop is a physician. He, though is not of the caliber of Ridgeon nor the other doctors. He treats many of the common men and women who have no finances for the treatments the others are afforded to prescribe to their wealthy patients. Because of this Blenkinsop lacks the wealth of his colleagues. Blenkinsop reveals that he, like Louis, has tuberculosis. Ridgeon chooses to cure Blenkinsop in order to ensure Jennifer becomes a widow for him to marry.
