Death in the East

by Abir Mukherjee

This is book number 4 in a historical mysteries series set in India during the Raj, with book no.3 already nominated for an Edgar. You could also read the series in order, but if you want to sample just one, Death in the East is particularly gripping. The story alternates between East London (before World War I) and a hill station in India (after World War I), with the two plotlines weaving together nicely.
