seven o'clock sharp
Now I 'm off to rest for a little while . '' `` I 'll follow your example . In the meantime I 'll give orders for an early dinner . '' We dined at seven o'clock sharp , and at half-past eight I went off to my room to don my disguise ; then , bidding the Marquis good-bye -- much to the young gentleman 's disgust , for he was most anxious to accompany us -- I slipped quietly out of my window , crossed the garden -- I hoped unobserved -- and then went down to the harbour side , where the boat I had chartered was waiting for me . A quarter of an hour later Wetherell 's carriage drove up , and on seeing it I went across and opened the door . My disguise was so perfect that for a moment the old gentleman seemed undecided whether to trust me or not . But my voice , when I spoke , reassured him , and then we set to work carrying the bags of spurious money down to the boat .
