Double trouble

"The troubles experienced by the hero ... are of the sort known to the gentleman whose personality alternated between that of Dr. Jekyll and Mr. Hyde. In other words, the story is of a dual personality .... Florian Amidon, a banker of Hazelhurst, Wisconsin, starts on a journey. He has not got very far when he suddenly and mysteriously becomes somebody else. In his new charater, it seems he is Eugene Brassfield, and with that name he wanders Bellevale, Pennsylvania, settles down, lives for several years, and becomes a leading citizen. One night, while on his way to New York he falls out of his berth in the sleeper, and the shock awakens him as Amidon, his existence as Brassfield becoming a complete blank. But his clothes, the papers found in his pockets, and the reception he meets when he reaches New York, all afford convincing evidence that he is Brassfield. One letter in particular shows him that he is engaged to marry a girl of Bellevale, who has the most unbounded affection for him"--The Dial review.
