eleven o’clock
During that night , therefore , the great blow was to be struck . Boxtel presented himself before Gryphus with a double supply of Genièvre , that is to say , with a bottle in each pocket . Gryphus being once fuddled , Boxtel was very nearly master of the house . At eleven o'clock Gryphus was dead drunk . At two in the morning Boxtel saw Rosa leaving the chamber ; but evidently she held in her arms something which she carried with great care . He did not doubt that this was the black tulip which was in flower . But what was she going to do with it ?
