Blackstone and the Scourge of Europe

Another case for the Bow Street Runner extraordinary. Napoleon Bonaparte, once the scourge of Europe, is now a tame captive on the island rock of St Helena. Or is he? When rumours grow of a plan to escape, Blackstone is sent by George IV to investigate security on the island. He finds a buzz of suspicion and intrigue among its ill-assorted population of effete garrison officers, native servants and ex-smugglers. Is the ex-Emperor being poisoned? Blackstone aims to find out. And then one night a 'monster' is sighted out at sea...

Blackstone and the Scourge of Europe is the fourth Blackstone novel.
