IN a snowy villa, with a sloping lawn, just outside the great commercial seaport, Barkington, there lived a few years ago a happy family. A lady, middle-aged, but still charming; two young friends of hers; and a periodical visitor. The lady was Mrs. Dodd; her occasional visitor was her husband; her friends were her son Edward, aged twenty, and her daughter Julia, nineteen, the fruit of a misalliance.
