Diamonds from Tequila by Walter Jon Williams
Sean Makin, a former child-star who suffers from a physical deformity, is shooting his feature film in Mexico along side his "tabloid girlfriend". However, things suddenly go south when he finds his "girlfriend" dead in her room and film's production & quality is put in jeopardy. Sean finds himself navigating Mexican authorities, DEA agents, and a shadowy prop assistant who has found ingenious uses for a 3D printer. Sean finds himself bribing local Mexican police to shot at windows then meeting a drug lord and then confront the man who accidentally killed his "girlfriend" to extort money from his corporate employers in an effort to save his one shot at a stable acting career. The story features several types of rogues and is very good, but sections of Sean's thoughts require you to have read Williams' book The Fourth Wall which lowered the rating.
