midnight
`` Do n't be , '' said Clo . She was up now , had pinned on the pretty white hat , and was fastening her smart little cape . `` I 'll go first to the Westmorland and see our man ; he said he 'd be in , waiting till ten . I 'll tell him things are in train , but he must give you till midnight , if necessary . From there perhaps I can ` phone the Dietz Hotel . It would n't be safe here . By that time O'Reilly ought to be in his room dressing for dinner .
