All Grass Isn't Green

All that glitters isn't gold.

A rich man sends Donald Lam looking for a man - when he really wants to find a woman. A minor missing persons case turns out to be a major one. And a pleasure boat on pontoons serves as a smuggler's ship on wheels.

This is a job for detectives who know their fact from fiction, and Bertha Cool and Donald Lam are pitted against people who know too well that all grass isn't green.
