The receptionist told Perry Mason there were two men waiting in the outer office; one of them looked like a prosperous banker, the other a tramp. One wanted to see him about some corporation law, and the other had a damage claim. So Mason said, “I’ll see the tramp. Tell the banker I can’t be bothered with corporation law.” But it turned out it was the tramp who wanted to sec him about corporation law. And that, in turn, merged into the story of one of the famous Lost Mines of the desert region of Southern California; of a sinewy little desert prospector and his partner, who had struck it rich, “housed-up” and, losing his health, had forsaken the big red-tiled mansion in the fashionable district of San Roberto to spread his sleeping bag out in the cactus garden at the far corner of the grounds. And finally there was the mysterious drowsy mosquito — was it a harbinger of death? These characters, together with the lure of a fabulously rich gold deposit, discovered more than half a century ago, then lost, and lying untouched year after year, waiting only for chance and the ingenuity of Perry Mason to bring it back into the limelight, make for a fast moving, baffling Perry Mason yarn
