“My dear Lemercier, of course I should not have intruded on you at this hour on a mere visit of ceremony. I called to say that the Mademoiselle Duval whose address you sent me is not the right one,--not the lady whom, knowing your wide range of acquaintance, I asked you to aid me in finding out.” “Not the right Duval?
