'Gerald, Sam and Ruby fly to India in Gerald's private jet for a holiday at the home of Alisha Gupta, looking forward to getting away from the exhausting business of stolen gems, bejewelled caskets, thieves and bumbling police officers. But their holiday soon turns to a desperate quest to outwit a deadly cult, and to beat Mason Green to the Emerald Casket in a fast-paced race against time and tide.' (From the publisher's website.)
