Mourning Raga — Ellis Peters

Dominic Felse and his girlfriend escort a young girl through India and investigate a murder in this mystery from the bestselling author of Fallen Into the Pit.

When his girlfriend's beautiful but erratic film-star mother, Chloe, calls to ask a favor, Dominic Felse fears the worst. But she makes the couple an offer they can't refuse: an all-expense-paid trip to India to escort Anjili Kumar, the fourteen-year-old daughter of Chloe's costar, to stay with her father while her mother is filming in England.

But Dominic's fears are not unfounded, and they soon discover that traveling with the spoiled, precocious Anjili is no vacation -- and the task of delivering her back to her family will be less than easy. For behind the colorful, smiling mask of India that tourists see, there is another country -- remote, mysterious, and often shatteringly brutal. . . .
