Autumn,1643. As an increasingly bitter war rages across England, Captain Innocent Stryker leaves Oxford with orders to recover a lost treasure, vital to the success of the Royalist cause. But a seemingly simple mission to the remote Scilly Isles is soon jeopardised, for enemies lie in wait. A formidable Parliamentarian agent has been sent ahead of Stryker's force, intent on defeating Royalist plans. Feared by ally and enemy alike, he is a man whose determination is only matched by his hatred for Stryker. The quest for the gold takes Stryker across storm-ravaged seas, through enemy territory and finally to the Royalist stronghold of Basing House. And it is there that Stryker will face his most dangerous challenge yet.
