It’s another day, another workplace injury compensation claim for Frank and Lu. The owners of an upmarket gift shop, suspect an employee of making a false compensation claim and need Lu and Frank to prove it. But Frank and Lu’s straightforward surveillance operation is derailed when one of the owners is found dead in what looks like a robbery gone wrong. Frank is unconvinced but is stumped when his prime suspects have cast-iron alibis. When the personal and professional collide, everyone becomes a suspect and Frank and Lu must use all their powers of detection to bring the real killer to justice.
