As a counterbalance to philosophical tales of European angst, I turned to this historical novel set in ancient Rome, hoping for a diverting dose of swords and sandals. The cover is misleading: the main character is not a soldier but Rufus, a young animal trainer whose gift with exotic creatures brings him into the orbit of the emperor Gaius, usually known as Caligula. There are swords, certainly, thanks to the Praetorian Guard; sandals, presumably; and some sand, courtesy of the arena. There’s even an elephant. But what this story really lacks is soul. Relying on coincidences, handily-overheard monologues and a rather lacklustre romance, it never really takes flight.
