The Great Hospital Mystery is based on one of Mignon Eberhardt's "Nurse Sarah Keate" whodunits. Physically and temperamentally, Jane Darwell at least approximates the middle-aged Sarah (here renamed Miss Keats), but otherwise the film runs far afield from Eberhardt's original concept. As the night superintendent of a metropolitan hospital, Miss Keats does her best to handle the personal problems of her staff -- especially nurse Ann (Sally Blane), whose brother Tracy (George Walcott) is being victimized by mobsters. To save Tracy from assassination, Keats and Ann make it appear as though he has died in the hospital while a patient there. Their plan is compromised when another patient is murdered -- or is he? Joan Davis provides gratuitous comic relief as a klutzy "girl in white."
