Few know more about what goes on in Singapore than Aunty Lee. When a scandal over illegal organ donation makes news, she already has a list of suspects. There's no time to snoop, though—Aunty Lee's Delights is catering a brunch for local socialites Henry and Mabel Sung. Rumor has it that the Sungs' fortune is in trouble, and Aunty Lee wonders if the gossip is true. But soon after arriving at the Sungs', her curiosity turns to suspicion. Why is the guesthouse in the garden locked up—and what's inside? Where is the missing guest of honor? Then Mabel Sung and her son, Leonard, are found dead. The authorities blame it on Aunty Lee's special stewed chicken with buah keluak, a local black nut that can be poisonous if cooked improperly. She's certain the deaths are murder—and that they're somehow linked to the organ donor scandal. To save her business and her reputation, she's got to prove it—and unmask a dangerous killer.
