In an unusual outing for The Saint, our hero conspires with the aunt of a spoilt heiress to teach her petulant charge some good manners by forcing her to accompany him on a 10-day trek by foot across Spain. The ostensible reason for this act of altruism on Simon's part is that the heiress is betrothed to his best friend. The aim, evidently, is to reform the woman-child before she inflicts a lifetime of misery on her husband-to-be.
The heiress is an utterly obnoxious, self-entitled brat, continually throwing tantrums when she doesn't get her way. She thoroughly deserves everything Simon metes out to her in this latter day Taming of the Shrew. Inevitably some critics will accuse the scriptwriters of sexism, misogyny, and a host of other gender crimes merely because the brat is a woman and her tormentor a man. I think that's humbug. If the shoe were on the other foot, and a stern matron was teaching a few home truths to a self-absorbed playboy, the same critics would be chortling with glee.
Not a bad episode, but it hardly ranks among the best. To me the biggest puzzle is what could have possessed Simon's friend to have proposed marriage to such a spoilt, narcissistic bimbo. He must have been hard up for cash or blinded by her feminine charms. In either case, he owes Simon more than he can know.
