Again Miss Lofts' royal personage -- in this case Isabella, Queen of Castile, who with her husband Ferdinand united Spain -- tells her story with the polite confessional recitation of a seat companion on a long distance bus ride, more to pass the time than really entertain. The problem here may be the choice of subject. Isabella, generally regarded as a shrewd, competent monarch, simply cannot have the same bursting-stays ""woman's"" treatment as the fiery Tudors, or other hapless royal pawns, Miss Lofts' specialty. And how does one deal with Isabella's acquiescence to the Inquisition, the expulsion of the Jews, the endless wars? She does, here, protest before giving in, but the author has her say at one point to Ferdinand, ""Now we can really move against the Moors. . . and then we will tackle the French."" Within the royal family there were multiple births and disastrous deaths, battles at which the Queen was present, and Christopher Columbus checks in -- but Isabella escapes even Miss Lofts' seasoned and successful mold.
