It's really a collection of amazing anecdotes, as memorized by a slightly strange child, but I'm ok with that. The stories are incredibly funny, and very telling of animal and human nature. Durrell seemed a very democratic child, so the liberal use of the word "peasants", even when the label really sticks, is the only uncomfortable note. Well, that and either Durrell or his family has a disproportionate share of crazy. Am in Malta, and read this around the time I took the most astonishing trip to the Blue Lagoon. The "natural" blue of the Mediterranean, just before it transmogrifies into the Blue Lagoon, is something Durrell tries to describe in any number of ways. "Blue Glass" is as close as he gets, but not by much. More like the course of the strongest blue blood.
His accounts of porpoises leaping in a moonless bay, mixing phosphorescent drops of ocean with thousands of fireflies is absolutely magical. Here's hoping the real Greece matches it in some slight way.
