the soft light of the afterglow it seemed to smile at him with a glint of
malice, like the treacherous thing it was. For Furnace Lake is
treacherous. The Big Earthquake (America knows only one Big Earthquake,

Just now the lake looked exactly like any lake at dusk, with the far shore
line reflected along its edge; and Casey's thought went beyond, to his
