It must have been these whispers—plus Carter's own statement to Parks and others that the queerly arabesqued silver key would help him unlock the gates of his lost boyhood—which caused a number of mystical students to declare that the missing man had actually doubled back on the trail of time and returned through forty-five years to that other October day in 1883 when he had stayed in the Snake Den as a small boy. When he came out that night, they argued, he had somehow made the whole trip to 1928 and back; for did he not thereafter know of things which were to happen later? And yet he had never spoken of anything to happen after 1928.
