Sixteen year old Evelyn Bellak kept a diary while hospitalized in 1918 as a patient with tuberculosis. The treatment regimen was called a "rest cure" because there were no antibiotics then. The diary, found in a library, is an impassioned account of both her illness and the social scene at the sanatorium, but it ends abruptly. Who was this girl and what happened to her? All of that has been a mystery until now.
