In this, actor Robert Hardy's fourth reading from Patrick O'Brian's celebrated historical novels, series heroes Jack Aubrey and Stephen Maturin are in very different circumstances from when we first meet them. In Master and Commander, the first of the series, Aubrey is young and full of himself, and through Hardy's performance we can practically hear Aubrey's puffed-out chest. But in The Hundred Days, Aubrey is a commodore, famous throughout the British Empire for his naval exploits, and Hardy reflects the confidence that comes with those accomplishments. Meanwhile, his best friend, surgeon-spy Stephen Maturin, is wasting away as the audiocassette opens, in deep mourning for his recently deceased wife. But soon enough, both are pulled into great adventure again--in this case, Napoleon's final campaign--and the fate of the Empire rests on their ability to stop the fitting out of a new French fleet and to keep a shipment of gold from reaching a mercenary army.
