Graham Greene is an expert in matters of love, but despite his surprising conversion to the Catholic Church, he is not an advocate of marital fidelity. Straying from the path does not necessarily mean experiencing a fiery adventure. It can just as easily be tinged with melancholy or proceed hesitantly. In any case, one should heed the advice of good friends, pedantic teachers, or kind writers if one does not want to hand over their spouse to the nearest passerby after the first (possibly unsuccessful) post-wedding nights. But beware: danger also lurks in the dusty middle phases of marriage. As always with Graham Greene, one embarks on journeys with him. For where could infidelity be more delightful than on the Riviera, where one can also acquire antiques at a bargain and the sentiment of 'Je ne regrette rien' seems to hang in the air?.
