Just finished this today.
I have to say that i loved this short story. Told in a beguilingly simple manner yet somehow timeless and grand in some other inexplicable way. Dont know what it is exactly but you just get the sense that you are reading a sheer classic.
The surprise factor when it comes is - seems to be a very intriguing and original idea.
The one flaw maybe that the reader is left with a feeling of wanting more. There is the sense that the protagonists might still yet, just maybe - have something up their sleeve...
