Daffodil Duckworth and the Fictitious Nazi Spy Ring

Daffodil Duckworth is a thirteen-year-old girl who is soon to learn that she has a high intelligence quotient and that the British government is looking for children with exceptionally high IQs for a special department in the hope of shortening the war with Nazi Germany. The special department is based at Uppingham School in the County of Rutland that was founded in 1584 and its work is in decoding German military messages, creating new codes, designing new code breaking machines, and its cover story is that it is a special department for gifted children. Daffodil is delighted to learn that the school once taught her favourite actor Boris Karloff. While at this school, she becomes very suspicious of one of the male teachers and decides to investigate him. One night, she follows him to Eyebrook Reservoir and witnesses him filming an Avro Lancaster bomber dropping a very special bomb; it bounced! Daffodil and three of her friends keep the teacher under observation; however, unbeknownst to them they are being observed by MI5 officers. MI5 thinking that Daffodil and her friends will destroy the operation involving the German spy, who is calling himself Mr Carter, decided that they must tell them the truth and perhaps have them to work with them. When Daffodil and her friends discover the truth about the German spy, they are very pleased to help MI5 keep the spy under observation. At the meeting, they meet someone, who MI5 thought they could help to become a great double-agent. The person, who MI5 thought that they could turn, was known to them under his cryptonym of 'Garbo' and to the Germans as 'Arabel'. Will they save the RAF's operation from being discovered by the German spy and can Daffodil and her friends assist the British Government and help 'Garbo' be accepted as a German Spy or will the fact that he is a Double-Agent be discovered?
About the Author: Demetrian Shallows has a B.A. in Single Honours Classical Studies from the University of Wales, Lampeter. He lives in the village of Bardney in the county of Lincolnshire. "I was born in the city of Lincoln, in the county of Lincolnshire in what I call the Province of England. I do not regard Scotland, Wales, Ulster, and England as nations, but as provinces, and I believe that a new Act of Union should be created. In creating a new union the Province of England will finally have what the other provinces have, its own Provincial Parliament, and the Provinces of Scotland, Wales, and Ulster will not keep asking the National Parliament for more powers. By creating a new union, the Premiers of all the Provincial Parliaments (note I do not refer to them as First Ministers for we should model ourselves on the Commonwealth of Australia, and Canada where the Heads of State, and Provincial Parliaments are called Premiers) will have equal powers and not keep asking the Prime Minister of the National Parliament every five years or so for new powers. I plan to use in all of my books to refer to Britain as the United Provinces of Greater Britain either under the name of Demetrian Shallows, or Llanwoeseth Mardis or under my other nom-de-plume of Dorian Thames Wells. This should prove my strength of feeling that Britain should undergo a change to become the United Provinces of Greater Britain." My hobbies and interests are family history, genealogy, armory, heraldry, and all allied subjects
