The hippopotamus in Stephen Fry’s eponymous novel is Ted Wallace—a failed poet, a failed theater critic, husband, father, and much else, too, that is not particularly successful. After being fired from a newspaper, Ted receives an unexpected offer from his goddaughter Jane, who has mysteriously recovered from leukemia. Her healer, David, is another of Wallace’s godsons and the son of Wallace’s best friend, billionaire Logan. David is a teenager with astonishing abilities, which attract a motley crowd to the Logans’ mansion. Everyone wants miracles from the boy; respectable society expects a Messiah and the creation of whiskey from water, and only the old rascal Wallace sees the frightened teenager in the awkward stage of adolescence. Wallace must delve into the history of the Logan family and learn what it is—what method—that David uses to perform his wonders.
