At home in California, Penn encounters a sumptuously beautiful red haired woman in his favorite cocktail lounge, the Blue Heron. And the adventure begins.
Three clues, three blue herons, are found in a dead woman's purse; an odd key, a cryptic note and a photograph. The adventure entails long forgotten Chinese tunnels in San Francisco, car chases and gun play, as well as a secret installation in the jungles of Nicaragua.
Who or what is the third blue heron? The one bad thing; the one blue heron evading him?
One Bad Thing; One Blue Heron.
