Girls' Dormitory Bande son (1936) BO

Dr. Stephen Dominick is the head of a German girls' finishing school and a published author who is very popular with his students. After Professor Augusta Wimmer, a snooping busybody, finds a love letter in a wastepaper basket, she goes immediately to Dominick and demands an inquiry to determine the writer's identity. Handwriting comparisons point to Marie Claudel, a 19 year old French girl. Despite threats, the senior refuses to disclose the object of her affections. Could it be the headmaster?
