Soon our heroine finds her identity increasingly "tangled up" with the volume and with Dottor Postiglione, a man with an instinct for happiness--but also one for self-preservation.

Much of the book's pleasure stems from Robert Hellenga's easy knowledge, which extends to Italian complexities. Where else would you learn that, in cases of impotence, legal depositions are insufficient: "Modern couples often take the precaution of sending postcards to each other from the time of their engagement, leaving the message space blank so that it can be filled in later if the couple wishes to establish grounds for an annulment." Luckily, however, there are also shops that sell old postcards, "along with the appropriate writing instruments and inks."
