When Imogen comes to. . . in a nursing home? . . . drugged for sure--her legs are like ""boiled macaroni"" but they don't stay that way long. In fact she's quite spunky even though she doesn't know why she's been kidnapped--apparently she's being used by her father's opposite number who's doing competitive scientific work. With Keen, the young man who's her custodian, she travels from place to place and so does the story, rather than from incident to incident. It's slight to be sure but more contemporary in tone than earlier Storey books with menace yielding to tacit understanding between Imogen and Keen which only Imogen in time can assimilate. Simpatico.
