Some good -- and some not so good -- touches in a gent on the jump yarn, as a yieti of sia is confronted with three identities, two women, a murder charge, and gang threats, as parts of his probable background. His inquiries lead him into death traps and murder, and from Los Angeles to San Francisco he pieces together evidence, until, not only does he clear himself to the police's satisfaction but is also able to revenge himself on the gang, and be sure of his real identity. Zippy.
