A long-buried family secret resurfaces when one of Aloysius Pendergast’s most implacable enemies shows up on his doorstep as a murdered corpse. The mystery has all the hallmarks of the perfect murder. The gem leads Pendergast to an abandoned mine on the shore of California’s desolate Salton Sea, which in turn propels him on a journey of discovery deep into his family’s sinister past.
