If you enjoy the Perry Mason stories you’ll enjoy the Cool and Lam mysteries...written under the pen name A.A. Fair. Lam was a lawyer who was disbarred for telling how to commit a murder and get away with it. The novel resulted in the law in California being changed. He applies for a job with the B.Cool Detective Agency. The B stands for Bertha. Eventually Donald Lam supplies the brain and Bertha supplies the brawn.
"We don't have any law here. Just a graveyard." LL from TREASURE MOUNTAIN
