The work centres on the lives of the somewhat eccentric Obeysekere family, in particular Sam, and the 1930s setting explores themes of colonization in Ceylon, now called Sri Lanka. Michelle de Kretser is originally from Sri Lanka. The title refers to a fictional case involving the murder of an English planter in Ceylon, which Sam Obeysekere, a lawyer, attempts to solve. Time Magazine named the book as one of the five best novels of 2004, referring to the date published in the United States.
