On all perishable goods meant for human consumption, there is a mandatory "Use by..." date. Something similar needs urgently to be devised for literature, or what passes off as a literary offering nowadays. What has definitely gone off and acquired a distinct pong by now are novels by nri housewives on the immigration experience (contents include sexual abuse, cultural shocks and syrupy nostalgia). At the centre of most such novels is a young girl, often brought up in Calcutta because there is a morbid attraction between BengaliNRIs and novel writing (Bharati Mukherji, Sunetra Gupta, Jhumpa Lahiri, to name just a few). The cast includes several hysterical or fey Bengali women: aunts, grandmothers et al who can read signs in vegetables, cook up storms in their kitchens and swish ominously through the life of our Bengali heroine, chanting mantras, telling apocryphal stories and deciphering omens.
