It's been two weeks since the events in the English countryside. Two weeks since the diamond casket was opened. Two weeks since Mason Green disappeared with an object that Gerald's family had been keeping secret for centuries. And while everyone knows that Green will resurface again, no one knows what his next move will be. No one . . . except Gerald.

Breaking into Green's room at the Rattigan club, Gerald, Ruby and Sam discover that the diamond casket was actually one of three ancient boxes containing objects of great power. After our heroes accept an invitation from Mr. Gupta to visit India, they discover that it may be the resting place of the emerald casket. But India holds more than just the casket: it also has assassins bent on stopping them at all costs, a great city under the sea, and Alisha Gupta, who Ruby can't stand, and Gerald and Sam can't see enough of.

Richard Newsome has crafted a sequel that more than delivers on the promise of the first book, and sets us up for a breathtaking conclusion.
