Ralph Henry Barbour,
Joan of the Island
(1920)
“ Indeed, Joan had noticed, ever since Keith arrived at Tao Tao, that there had been a gradual change creeping over him. At first he was preternaturally serious, and there was a hard look about his mouth which only relaxed in rare moments of merriment. Nowadays he was becoming more human. The careworn expression flitted across his face like a shadow at odd moments, as when he was gazing out into the unknown, over and beyond the horizon, but it vanished as quickly as it came. Joan never tried to peer under that mask of gloom which dropped over his face at times. ”
