The green eye of Goona

The priceless green diamond belonging to the Rajah of Goona has been stolen, and Harvey Crooks has been asked to bring a case of Imperial Tokay wine to England for an acquaintance named Hahn. But one of the bottles has more in it than a rare green wine--a fact Crooks only learns after he has sold the wine. With Hahn and several others also after the diamond, it's a race to get the bottles--and to stay alive.
