in the ambassador's study underneath the oil painting of himself, the prime minister is escorted to a telephone by the butler who hands him the instrument. having been told who was on the other and of the line he is all smiles as he greets jo. having strummed a few notes, jo settles down and plays the introduction to her song. we see the great tenseness on her face, interposed with professional smiles, which she bestows on those nearest her, but always the tenseness returns. as she sings, her voice seem to be rather overpowering. it fills the whole room with quite a volume. it almost seems out of place that she has become so professional in such an intimate drawing room setting. mrs. drayton's face shows a new and dangerous thought coming into it. she looks down at hank. down in the ballroom, jo is looking up anxiously as she sings. she deliberately breaks and pauses for a moment and softens her accompaniment. then she hears it -- a faint whistle coming from above, not enough for those around to appreciate it, but loud enough for the straining ears of jo. she looks across the ballroom to find ben, and her eyes go up. the door handle turns quietly, but firmly. drayton seems unperturbed by ben's refusal. he leans down closer to the boy, and addresses him directly.
