About two o'clock
She was haunted by visions which sleeplessness enlarged to a gigantic size . Then an idea took root in her brain . In vain did she strive to banish it ; it clung to her , surged and clutched her at the throat till it entirely swayed her . About two o'clock she rose , rigid , pallid , and resolute as a somnambulist , and having again lighted the lamp she wrote a letter in a disguised hand ; it was a vague denunciation , a note of three lines , requesting Doctor Deberle to repair that day to such a place at such an hour ; there was no explanation , no signature . She sealed the envelope and dropped the letter into the pocket of her dress which was hanging over an arm-chair . Then returning to bed , she immediately closed her eyes , and in a few minutes was lying there breathless , overpowered by leaden slumber . It was nearly nine o'clock the next morning before Rosalie was able to serve the coffee .
