This is book number 12 in the Sharon McCone Mysteries series.
Since the Gold Rush, California prospectors have siphoned off the waters of isolated Tufa Lake, exposing the fragile, otherworldly mineral formations of the lake basin. Now a local environmental group seeks to block the latest incursion by developers--a massive mining operation funded by TransPacific, a US-Hong Kong interest that seems to be behind a series of break-ins, disappearances, and shady land deals. Into this stark, lunar landscape treads San Francisco PI Sharon McCone, searching for a local eccentric now missing after a suspicious land deal. When the bullet-ridden corpse of an investor surfaces in the lake's silvery waters, McCone finds herself on a twisted trail that leads to San Francisco and then back to where it all began--the eerie desert mesas where a murderer prepares to kill again.
