Pearl Green and Karen (Kaz) Henderson are two successful Hong Kong women, whose old friendship brings them back together after many years to set up an archaeological project for Pearl's philanthropic organisation, the Hong Kong-based June Bowen Foundation. Karen, an archaeologist acclaimed for her work in Southeast Asia, is injured during a robbery at the Hong Kong Archaeological Museum. One of a number of stolen objects is associated with Pearl Green's past. The Museum Director, Albert Ho, is professionally jealous of Karen and convinces himself that she stole the artefact for Pearl. He hires a shady new arrival to Hong Kong - BJ Cresswell - to get it back. The lives of Pearl and her friends come under threat. Pearl seeks help from three men: her father, the powerful Sir James Gates; the mysterious Hong Kong businessman, Yip Yee Koon and the British former China Watcher, Peter Benson. Together, they masterfully untangle the many threads of murder and intrigue that run through this story.
