eleven o’clock
`` In the Italian Quarter ? '' `` No , I fancy Chiswick is an address which is more likely to find him . If you will come with me to Chiswick to-night , Lestrade , I 'll promise to go to the Italian Quarter with you to-morrow , and no harm will be done by the delay . And now I think that a few hours ' sleep would do us all good , for I do not propose to leave before eleven o'clock , and it is unlikely that we shall be back before morning . You 'll dine with us , Lestrade , and then you are welcome to the sofa until it is time for us to start . In the meantime , Watson , I should be glad if you would ring for an express messenger , for I have a letter to send and it is important that it should go at once . '' Holmes spent the evening in rummaging among the files of the old daily papers with which one of our lumber-rooms was packed .
