"Police, hurry up and catch her! The infected woman has escaped!! That disgusting little woman is getting away!!"

- Dr. Soper

Dr. Soper (Dr. ソーパー) is the main antagonist of The Ultimate Choice That Actually Existed: Typhoid Mary, the fourth chapter of The Lives of Eccentrics series.

He is a sanitation engineer who works with the New York police on catching Mary Mallon.

Appearance
Dr. Soper is a man of average height and build. He has short blonde hair and vertical cat-like pupils.

He wears a suit with a vest, tie, and fedora.

Personality
Dr. Soper appears to be a man who can mask his emotions very effectively to appear calm and approachable; when Mary Mallon leaves the room through the window during her interrogation, Soper immediately dropped his affable persona and, in a fit of rage, called her a "disgusting little woman". Soper seems to despise Mary Mallon for refusing to cooperate and continuing to cook infected food.

The Ultimate Choice That Actually Existed: Typhoid Mary
Following the incident of summer, 1906, where many of the attendants of a party in were hospitalized after eating Mary Mallon's food, Mary is interrogated by Dr. Soper. Despite her cheerful demeanor, the mention of the ill guests provokes her into defending her cooking. Soper explains that the guests have fallen ill with typhoid fever, a potentially-lethal disease with a mortality rate five to seven times higher for elderly people and infants. Soper raises the possibility of Mary being a healthy carrier whose gallbladder has been infected, and proposes taking her to a doctor. Upon hearing this, Mary seemingly jumps out a nearby window and runs, forcing Soper to send the police after the "disgusting little woman." Suddenly, Mary reappears and, enraged by Soper's comment and defensive about her health, spits on the police officers before making her escape.

In 1915, Mary reappears at the home of an old blind man and his infant child. After drinking a bit of the baby's milk, Mary prepares to give it to the baby, certain that her cooking makes people too happy for them to be suffering from it. Fortunately, a series of coincidences barely keeps the baby away from the bottle of milk long enough for Soper and the police to arrive. Mary, cornered, attempts to flee through a window once more, only to be arrested again. Since her release, she had resumed cooking under a false name, and had infected an additional 25 people.
