The latest installment in Alexander McCall Smith's charming and hilarious Professor Dr Moritz-Maria von Igelfeld series

His eminence in language studies is widely respected, albeit rarely acknowledged by his colleague, Professor Detlev-Amadeus Unterholzer, the writer of a far less important book on the subjunctive. Their rivalry bubbles under the surface, but is quick to come into the open if something unusual disturbs the calm waters of the institute in Regensburg where they both work.
