Unusual Uses for Olive Oil in Great Britain. It is now available here, too.
Fans will remember the professor is very protective of his reputation and spars frequently with his academic rivalries over very obscure points of philology, manners, and department etiquette. He also gets to travel to conferences to present the same lecture over and over to the same group of academics. He often finds himself in ridiculous situations of his own making. He was, of course, especially hurt when he saw a copy of Portuguese Irregular Verbs that he had given to a potential love interest used as a foot stool.
In Unusual Uses for Olive Oil, life continues for the silly Dr Dr, but I sense a little more sympathy in his soul. Not enough for him to fall truly in love or put others first, but he does seem to learn to look more kindly on the department's talkative librarian Herr Huber.
If ever there is a man who really needed a valet, it is Professor von Igelfeld. Read Unusual Uses for Olive Oil and you'll see why. By the way, you will not learn about the olive oil until the final chapter.
