Even I was thoroughly confused when I read the first few pages of N.Nayaki - which begins after 9 year rigerous imprisonment of V.Devan. Even I thought it is a historic truth and was taken aback as to how this fellow really managed to marry Kundavi at all - having been framed like that ! But apart from that novel, I've not come across any evidence to support this. True, I may be ignorant of some evidences - But I'm almost convinced that this is nothing but imagination of Vikraman.
Also - With due respects, I've to say that the novel is not a good work at all. The preface raises great expectations - it says it is meant to answer many questions raised in PS - but I don't think it is worth reading even once.
Atleast I would not recommend it to anybody I like :-)
