Referat ENIGMA




ENIGMA

by ROBERT HARRIS

·      ENIGMA is the name of a German decipherig machine, which is until nowadays worth to be a technical wonder.

·      At BLETCHLEY PARK was the English Cipher Bureau during World War II.



Th book is about Thomas Jericho who worked as a cryptoanalyst during World War II at Bletchley Park. There he got into contact with a young and good-looking British undercover spy, Claire Pomilly. About in the middle of the story she suddenldy disappeared and during his investigations he got into a German spy syndicate, led by Adam Pukowski, and destroyed it.

Characters:

Thomas R. G. Jerico:

After his father´s early death his mother married another man, whom he disliked, so he found astronomy and mathematics. He matriculated in 1935, Senior Wrangler, Mathematics Tripos in 1938. At Cambridge University, theth teacher, Frank Atwood sent him to a friend who led him into the art of deciphering. On December 4th 1939, three days after Germany has invaded Poland, he begen to work at Bletchley Park. There he met Claire Romilly with whom he had a short affair. In January 1943 he had a physical breakdown and was sent back to Cambridge University a short time after he deciphered the German-naval code "SHARK". Soon after his breakdown the German naval-forces surprisingly changed their ENIGMA codebooks and so he was again called back to Bletchley Park. Back there he met Claire again and he fell in love with her but she ended their affair abruptly.

page 63:  "a mathematican, like a painter or a poet is a maker of patterns."

page 65: "Jerico thought the ENIGMA machine was beautiful - a masterpiece of human         ingenuity that created both chaos and a tiny ribbon of meaing."

page 287: "I´m a mathematician, not a moral philosopher."

Hester Wallace:

She grew up in Dorset, went to school at an eccentric girls´school at Beamister. Through her gift for crosswords, she came to Bletchley Park by winning a crossword competition of the Telegraph. She lived in the same house as Claire, so she got into contact with Jerico, when he tried to find Claire. She became a very close friend of Jerico during their search for Claire, as both of them knew, that they needed each other´s help to solve the mystery of Claire´s disappearence.

Claire A.Rommily:

She pretended to be born in London in 1921, educated privatly abroad, after her mather´s decease in 1929. Her father worked all over Europe in his job as a diplomat, even in Berlin for two years. She finished her education in Geneva and returned to London on the outbreak of war, in the age of seventeen. After a few of voluntary jobs at civil defense she got a job as a translator in 1941 at the Mnistry of Economc Warfare. Then in 1942 she applied for clerical position at the Foreign Office. Because of her well knowledge of languages she was recommended for a position at Bletchley Park. So she started working at the store building in the Park. There she had an affair with Jerico, but she ended the relationship, because she loved another man, Adam Pukowski. Later she dissapeared surprisingly.

 Adam Pukowski:

His mother was English, his father Polish. He lived in London till he was ten, when his parents             got divorced he went away with his father to live in Cracow. The father was a professor of mathematics, the son showed the same aptitude and found his way to the Polish Cipher Bureau at Pyry. When the war broke out the father was called up to the rank of a major to rejoin the Polish Army. Defeat came. Half of Poland was occupied by Germany, the other half by the Soviets. His father disappeared. Puck escaped  to France to become one of the fifteen Polish cryptoanalysts, employed at the French Cipher Centre at Gretz-Armainvillers. Defeat came again. Puck escaped to neutral Portugal, where he made the acquaintance of Rogerio Raposo. From Portugal he found his way to England, where he worked at Bletchley Park. Two yars passed with no news of Pck´s father or any of the other ten-thousand missing in action Polish officers. In 1941, afterwards Germany has invaded Russia, Jossif Stalin unecspectedly became a British ally. Two years later rumours begen to circulate among the Poles in London, that these missed officers have been executed and burried in a forest nearby Smolensk. Then the day came Puck found out that one of the victims was his father.

page 350: "I killed her, Thomas i´m so terribly sorry!"  




                        page 287: "THe presumption that the onus is on us to make a moral choice."

Guy Logie:

Before the war Logie had been head of mathematics at a vast and ancient public school. He had a Blue in rugger and another in hockey and "irony bounced off him life pebbles off advancing rhinoceros" (page 21).

Logie is the head of the chief cryptoanalyst at Bletchley Park, so he was the man who took Jerico back to the Park after his blackout.

Leonard Skinner:

He was the head of the naval section at Bletchley Park, and so he wa Jerico´s superior. He didn´t like the way Jerico behaved and he wanted him out of the Park.

page 91: "Thank you, Tom. Thank you very much indeed. I´d forgotten what a tower                 of strenght you could be."

page 93: "You are an ill man, Tom. And I´m stonger than you in every way.

Officer Wilgram:

He was the chief of Blentchley Park´s secret service, so he was the person who sent           under-cover agent Claire Rommily to Bletchley Park to infiltrate the cryptoanalysts. He knew everything about Puck´s daed father but he still let Puck run into the trap  and later shot him when he tried to escape to Germany.

page 367: "No I´m sure Pukowsky never even told Claire for just one minute what he was planning to do. Consider it from his point of view. She was the weak link. She could have given him away any moment. So iI imagine how he must have felt when he saw you walk back through the door from Cambridge on that Friday night."

Plot:

On a Friday evening in February 1943 Logie takes Jerico from Cambridge University back to Bletchley Park, where he is confronted with the problem that German submarines have changed their comunication codes and that three American convoys, with 117 merchant ships, 9 000 merchant seamen and about 1 000 passangers, have just reached the middle of the Atlantic. Suddenly his ex-girlfriend Claire doesn´t come to work, and so he starts to search for her. During that he finds classified documents in her room. Later he discovers that on these sheets are deciphered radio-transmissions from a German unit in Poland to the GeStaPo headquartes, which have just discovered a mass execution of Polish officers in a forest near Smolensk by the Soviet army. Among the dead also is Adam Pukwskißs father, a decipherer at Bletchley Park,  who hates from then on the Soviets and their Allies. So he becomes a spy for the Germans and later tries to escape to Germany. But on the train to his meeting with a German submarine, Jerico finds him and when he tries to escape he is shot by the police.

Language:

                       

The language used in "ENIGMA" is most of the time easy to understand, although I do not think that the book especially was written easy to understand, because in some parts their is used a lot of military language, which is really hard to understand as a civilist.
