The success of the first book paved the way for the sequel "Konkal Dip" (Skeleton Island). The third installment was "Rupali Makorsha" (The Silver Spider). Later a new book was published every month. Most of the books were adaptations, mostly from western writers. This lack of originality was criticized. It was initially based on "The Three Investigators". Later books were based on other western detective juvenile thrillers. The first 40-45 stories are from Robert Arthur, Jr's "The Three Investigators". These stories have David Christopher on them. Original 'The Three Investigators (1964-1987)' series published by Random House (world's largest general-interest trade book publisher) in English had 43 books written by Robert Arthur (10 books), William Arden whose original name was Michael Collins (13 books), Nick West (2 books), M. V. Carey or Mary Virginia Carey (15 books) and Marc Brandel (3 books). Two movies in English were made by a German-South African production house. The first movie was ‘"The Three Investigators and the Secret of Skeleton Island" (2007)’ and then ‘"The Three Investigators and the Secret of Terror Castle" (2009)’. These two movie plots were slightly different than the books and the updated story included technologies like GPS and mobile phones.  11 books became the next series called 'The Three Investigators Crime Busters (1989-1990)'. Two of these books were written by original series writers, one by William Arden and another one by Marc Brandel. Other writers of the ‘Crime Busters’ series were Megan Stine and H. William Stine, G.H. Stone, William MacCay and Peter Lerangis. The stories which have Georgina Parker or Gina for short on them are from British author Enid Blyton's The Famous Five (1942-1963). She wrote 21 books. Television series were made in 1977 and again in 1995. The name Gina and eventually her full characteristics were based on the series. Other characters were transformed into Tin Goyenda by Hasan. The Famous Five series included two brothers and a sister whose cousin was ‘Georgina Kirrin’. These characters were transformed into the characters of Kishore, Musa & Robin. Their cousin Georgina had the dog named ‘Timmy’ which was called ‘Ruffian or Rafi’ in the ‘Tin Goenda’ series.
