Sixty-year-old Vera Wong enjoys nothing more than sipping a good cup of Wulong and doing some healthy ‘detective’ work on the internet (AKA checking up on her son’s dating life). But when she wakes up one morning to find a dead man in the middle of her tea shop, it’s going to take more than a strong Longjing to fix things. Knowing nobody sniffs out a wrongdoing quite like a suspicious Chinese mother with time on her hands – Vera decides it’s down to her to catch the killer.
