He promised faithfully to be home by three o'clock and it's nearly five now. Unless we start soon we'll never get to Sunset Beach tonight." Penny Parker, in blue slacks and a slightly mussed polo shirt, gazed disconsolately at the over-loaded automobile standing on the gravel driveway of the Parker home. Aided by Mrs. Weems, the family housekeeper, she had spent hours packing the sedan with luggage and camping equipment. Though the task long had been finished, Mr. Parker failed to arrive. "Your father is a very busy man," Mrs. Weems responded to the girl's question. "No doubt he's been held up at the office." "Then why doesn't he telephone? It's driving me crazy to wait and wonder."
