four in the morning
`` Durrance went down to Tewfikieh at ten o'clock that night , '' said Calder . `` I went to his quarters at eleven . He had not returned . He was starting eastward at four in the morning , and there was some detail of business on which I wished to speak to him before he went . So I waited for his return . He came in about a quarter of an hour afterwards and told me at once that I must be quick , since he was expecting a visitor . He spoke quickly and rather restlessly .
