内容简介：
Actually five books in one, Return to Lmuma is a continuation of life and love for three teenage boys introduced in Mystery of the Lmuma Mine. Ron Martin, Wildlife Photographer and Explorer tells his story of adventure, murder, and lost treasure in Mexico, Africa and Arizona. Rex Franklin joins the US Navy as a Frogman and sees plenty of action during the Korean War. Rex is charged with murder, but proves instead to be the scape-goat victim of a large political scam. Tim Caruthers is a top notch fire investigator for the Portland Fire Bureau. Lots of gritty smoke filled action until Tim finally outwits the serial arsonist. Reunion at Lmuma Mine: Some 40 years after the original Lmuma Mine story (also included), the three main charaters (now retired) return to see if they can find the old mine. Some town people are cooperative, but many are not. The mine is located but found occupied by big money criminals
