We now believe that the fabled "Sackett's Gold" (Bantam, 1977) exists only as a database error, perhaps based on a cover blurb for "Treasure Mountain", copies apparently for sale online being misassigned (and out-of-date) citations of another L' Amour novel (Borden Chantry) sharing the same ID number.
