Here is a “Mrs. B” case. The subject, Miss W——, during the year 1912, met a Mr. and Mrs. M——, Americans, who were in Paris with their two children, a boy ten and a girl twelve. Miss W—— told them a story of having quarreled with her family, who were quite wealthy, and said she was seeking a position that would bring her to America. She produced unquestionable references, and returned with the M—— family to the United States. After remaining in their employ for six months, she took a course in nursing in B—— Hospital in Indianapolis. She graduated from this hospital, came to Chicago with letters of introduction from the faculty, and became engaged here as governess in the home of a wealthy family on Lake Shore Drive. In April, 1917, she applied to the Chicago Telephone Company for a position, asking to be sent to France in their next unit. She told a confusing story in reference to her age, brought about a suspicion, which was followed by an investigation. “Mrs. B.” was given the assignment. Miss W—— gave up her position as governess, took a room on the north side of Chicago near Wilson Avenue. She was closely shadowed night and day, and was found to be in continual communication with doctors and nurses. During the time she was waiting to hear from the Chicago Telephone Company in reference to the application she had filed, she also filed an application with the American Red Cross. Here she gave practically the same references, and told the same story. Investigators from the American Red Cross were advised by the Department of Justice that they drop their investigation for the time being. “Mrs. B” proved that this woman was the medium through which tetanus germs were being delivered to certain doctors and nurses, who in turn were to spread them through our cantonments and hospitals.
