Hi 1-march the anniversary of the hydrogen bomb- 1954 kalki must have read it in the papers on 2nd or so and in him came the spark of a story
"mayil vizhi maan" perhaps kalkis last completed story - much of it was written from a hospital bed. published in the deepavali malar of kalki magazine.
its about a ancient tamil civilisation settled in a distant island, and the hero of the story gets air wrecked there , and predictably falls in love with the princess.' the island is destroyed by an american government sponsered hydrogen bomb test.
