Erle Stanley Gardner 
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.
