Little does Dee Carmichael know as she prepares for the final Bombay expatriates' annual cocktail party what surprises and horrors the evening is to bring. Encouraged by an anonymous tip-off to revisit an old case, police inspector Tommy Morrison has discovered that a handsome blonde woman found dead on an Indian train in 1969 was actually murdered. Worse still, the woman was his sister's illegitimate child, given up for adoption at birth. Now, as the dead woman's friends, husband, daughter and lover gather to reflect on the passage of their lives since they left Bombay, Morrison will take them back to the heat-sullied, passionate days of 1960s India to reveal exactly why and how Sonya Richards was murdered - and who her killer was.
