midnight
Since the chart was in a safety-deposit vault we felt pretty sure of ourselves , for he would have to secure it between the time we took it out and our arrival on the _ Argos _ , at best a spare half hour in the middle of the day . But since the captain did not know what we had done with the document , it was a good guess that he would have a try at searching for it . On the evening of the third day before we were due to sail , Blythe and I took Miss Berry and her niece to the opera and afterward to a little supper at a cozy French restaurant just round the corner from the Chronicle Building . It was well past midnight when we reached the hotel where the ladies had their rooms . Miss Wallace had no sooner flung open the door than she gave an exclamation of amazement . The room had been fairly turned upside down . Drawers had been emptied , searched , and their contents dumped down in one corner .
