Meantime, Julia, Mason's wife, goes on a little joy ride with Jack Trent, husband of Vivien, her friend who is on a joy ride with Mason's father, a delightful old rogue. Gladys, Julia's hoydenish sister with whose photo Uncle Bill has previously fallen in love, is left home alone. While she is reading "Oiley" enters by the alcove window and hides. Uncle Bill, on his arrival m town, stops at the "café," recognizes Julia as she passes him to enter the café with Jack and follows them in, taking a seat nearby.
