AUGUST 18,2008. In the wee hours of the day, the river Kosi breaches the embankments in Kusaha, Nepal, leaving in its wake an awesome trail of death and destruction downstream in Bihar's northern plains. Panic-stricken, people run helter skelter ooking for high ground, railway tracks, trees, whatever, to escape the swirling waters. At last count, on August 28, the death toll had touched 55.
