Keys of Hell

The Chief of the Bureau has a 'simple' job for Paul Chavasse - slip into Albania and eliminate a double agent. Then he can take a holiday. The innocent-sounding words are the prelude to a desperate race against time which leads Chavasse across land and sea in search of a priceless relic before it can fall into the hands of political extremists. With a diving expert and midget submarines to help him, what can go wrong? But a trap has been set. For him. By someone who has waited a long time for revenge. As his escape routes are remorselessly closed off, the indestructible Chavasse, whom no one could ever out-think or out-fight, is now headed straight for destruction - for Hell ?
