`` Why must you go to Glasgow ? '' `` They have got into a mess at the works there ; and the engineer has telegraphed for me to go down and see what is the matter . I shall certainly be back on Monday . Have something for me to eat at half past seven . I am sorry to be away from our Sunday dinner , Douglas ; but you know the popular prejudice . If you want a thing done , see to it yourself . '' `` Sholto has been very eloquent this evening on the subject of popular prejudices , '' said Marian .
