Spiro is a hulking and hairy Greek man who takes the Durrell family under his wing. Prior to the start of the novel he spent eight years in Chicago, which is where he learned English. This, according to him, makes him a favorite guide of all English-speaking tourists. He takes it upon himself to make sure the Durrells don't get swindled and fights with the local customs agent on several occasions to move the Durrells' belongings through without too much issue. Gerry notes that Spiro acts as though he owns the island, though Spiro regularly badmouths others that he believes act as though they own the island. Gerry refers to Spiro as the family's guardian angel; he becomes a friend and mentor during the family's time in Corfu. Spiro adores Mother and regularly reports to her when he sees the Durrell children doing anything potentially unsafe or of interest. He endears himself to Gerry especially when Gerry asks for help obtaining goldfish for his pond. Gerry discovers that Spiro stole the goldfish out of the palace where royalty and foreign dignitaries stay when they visit the island.
