William Boyd taps into the classical novel tradition with this sweeping tale of one man’s century-spanning life, even to the extent of providing the accustomed framing device: the chance discovery of a cache of papers and mementoes. The items listed by ‘WB’ in his ‘Author’s Note’ – a musket ball, a fragment of a Greek amphora, a crinkly lock of hair – all find their place in the tale of this 19th-century adventurer, lover, traveller and author. Cashel Greville Ross (his name turns out to be as mutable as his identity and nationality) is born in Ireland in irregular circumstances – so irregular that a swift flight to England as a boy is effected, the first of his many transitions. The temptation is great for authors who place fictional characters in historical settings to have them meet famous people along the way, but at least Boyd is knowing about it.
