The latest book in Alexander McCall Smith's entertaining and hilarious Professor von Igelfeld series Professor Moritz-Maria von Igelfeld is not just any German professor - he is the author of that great work of scholarship, Portuguese Irregular Verbs. His eminence in language studies is widely recognised, even if it is rarely acknowledged by his colleague, Professor Detlev-Amadeus Unterholzer, author of a much less important work on the subjunctive. Their rivalry bubbles away under the surface, but is apt to come into the open if something unusual disturbs the calm waters of the institute in Regensburg in which they both work. One such event is the arrival from New Orleans of two visiting scholars. These ladies, Professor Pom Pom Boisseau, and her friend, Professor Alice Martinique, are both experts in the Provençal language as well as being keen bikers. When they choose to arrive on large, noisy motorbikes, Unterholzer is shocked, but von Igelfeld is rather taken with Pom Pom.
