Mexico Is Forever — Benjamin M. Schutz

D.C. investigator Leo Haggerty will be fascinated to watch the savvy PI wield "the most dangerous tool in the world, the telephone." Starting with a few meager facts about beautiful, elusive Sarabeth Timmons--who may or may not be heir to a sizable sum--the methodical Haggerty and his staff uncover increasingly bizarre intelligence leading to a powerful Hollywood VIP, corrupt law enforcers, porn-film producers and murder. Fortunately for Haggerty, his many trustworthy friends are happy to extend helping hands as he sinks deeper into this moral morass.
