Fowl-Filcher is the title of the novel written by Ranga Rao. Fowl-Filcher is the story of the eponymous title (the fowl-filcher) is set in a hamlet surrounded by a jungle. Professor Ranga Rao taught at the Venkateswara College, University of Delhi.
‘Rao’s Fowl-Filcher bristled with rollicking laughter and it offered amusement at all levels – a full throated humour formed the format of the book.”- R. P. Chaddah, The Tribune.
Fowl-Filcher is a broad novel of many of India’s changes in the first decades after independence, and is especially appealing in its focus on smaller locales (while, in also moving beyond just village life, not remaining entire provincial). Fowl-Filcher’s varied life makes for interesting material, and Rao handles many of the episodes quite well, but the novel lacks the coherence of a true continuum, jerking forward too often.” –M. A.
