Alton Rhode knows a lot about murder and almost nothing about bitcoins. He soon gets educated about the latter with the help of an unorthodox but brilliant young woman. But his own expertise comes in very handy when he runs into a bunch of Russians and Chinese whose motives are both murderous and mercenary. With scenes in New York, San Francisco, and Florida, Golden Gate is a typical Alton Rhode mystery, full of mayhem, but with just enough biting humor to please every literary palate. Free on Kindle.
