The Chameleon Talisman jettison's ahead from where The Red Diamond trails off. Talya Solomon is now faced with a new conundrum. After attending Iwan Kowalski's funeral, a note presumed to be a condolence card is handed over to her by an unfamiliar man of Indian descent. She slides the unopened envelope inside her purse. Later, at the reception, she finds herself alone still haunted by best friend, Clarissa Stanford's murder. Upon opening the note, she realizes things aren't what they seem. A different diamond now has a new mark, Anna Pinsky, who has mysteriously disappeared with a green diamond called the Chameleon Talisman. Amit Pinsky has beseeched her with written words, "lives are at stake!" to help him locate his sister. This challenge takes Talya and partner, Tomas Anderkvist through the corridors of England, then onward to India, in search of Anna. Unfortunately, Talya and Tomas are in the crosshairs with countries vying for the Chameleon Talisman at any cost. Much is at stake as this diamond transgresses all concepts of faith with its hidden treasure.
