`` But just this once -- please , Olga . '' Laura 's eyes -- warm , loving , compelling -- looked into Olga 's , dark , sombre , and miserable ; and suddenly with a little gasping sob the girl yielded because she knew if she stood there another minute she would break down . `` I 'll -- come , '' she promised , and without another word turned and hurried back into the house . Laura was half afraid that she would not keep her promise , but at six o'clock she appeared . Jim fell upon her with a gleeful welcome , and she tried to answer gaily , but the effort with which she did it was evident , and earlier than usual Laura took the boy off to bed . `` Something is troubling Olga , '' she whispered as she tucked him in , `` and I 'm going to try to find a way to help her . '' `` You will , '' he said confidently .
