Based on one of the novels above, How I Met Myself, which is written by David A.Hill, I like the story because I have learned determination from John Taylor. For example, John Taylor was determined to find the man who ran into him at Felka utca. He followed the man in Zsolt's cafe. He looked for the man in cafe.
He went to Budapest City Library and read many old newpapers and found that a mother Mrs Szabo and her child died in an explosion in Gergely utca on 18 January and met the same man again but Andrea did not see anything. In addition, John Taylor was determined to find out about the Szabo family might relate to doppelganger. He went to see the housekeeper in Gergely utca to ask a Szabo family. He went to Public Records Office and discoved that John Taylor and Janos Szabo were born in 23 October.
