River of Death is a thriller by Alistair Maclean which happens around the Amazonian jungle. Maclean has always placed his settings within the confines of the most inhospitable environments. Here the protagonists have to battle the jungle with insects, piranhas, crocodiles and hostile cannibal tribes. He says something for the preservation of the old civilizations and the environment itself.
The story opens with the fag end of world war two, where at the docks of Wihelmshaven, the SS soldiers are loading crates of gold and precious stones in the submarine. General Von Monteuffel and Colonel Spatz head overseeing the loading of the crates. Spatz leave to check on the operations along the border with the Russians and the general promises to wait for him. Spatz returns with Russians and allies hot on his heels and is betrayed by Von Monteuffel who leaves him stranded at the dock.



As the flash back settles in, the story moves in a different direction. John Hamilton, is the archaeologist who has discovered a lost city deep in the Amazonian Jungle. As soon as he has made the discovery public, Smith a German millionaire who has a mysterious shady connection makes him a proposal of funding the expedition to the lost city. Hamilton agrees and along with his trusted lieutenants, Ramon and Navarro, he sets off to the Jungle with Smith and his henchmen, Hiller and Tracy. In the group, Smith's secretary Maria is also present.
As soon as they set in to the Jungle they get easily lost. They fight huge crocodiles and insects. Maria who seems to have developed a soft corner for Hamilton is saved from the anaconda who has almost devoured her. Ramon and Navarro seem the happy go lucky people who crack jokes and are never afraid of anything. The whole group run for their lives from the cannibalistic tribes.
They soon reach the destination and the action hots up. They discover a German settlement which is headed by General Von Monteuffel. Smith is revealed to be Spatz who was seeking them to avenge his betrayal. Maria turns out to be the secret agent from the Mossad. As the action hots up many are killed and Von Monteuffel is captured. Hamilton reveals to him that his actions were also to avenge the killing of his wife by the general. Soon huge treasure and the murderers are captured and brought before the world.
Maclean has given an innovative setting for a thriller but fails to keep the reader riveted in his seat. The Action sequences are too predictable and many work in favor of the hero. So there is no adrenaline rush or a special affection for the characters. But the tale is short and one can finish it in two hours. So if you are in a mood for some flippant reading, take it up.
