six o'clock
Newmark said nothing , but for some time thought busily , his light blue eyes narrowed to a slit . `` I 'll have to figure on it a while , '' said he at last , and turned back to his mail . All day he worked hard , with only a fifteen-minute intermission for a lunch which was brought up from the hotel below . At six o'clock he slammed shut the desk . He descended the stairs with Orde , from whom he parted at their foot , and walked precisely away , his tall , thin figure held rigid and slightly askew , his pale eyes slitted behind his eye-glasses , the unlighted cigar in one corner of his straight lips . To the occasional passerby he bowed coldly and with formality . At the corner below he bore to the left , and after a short walk entered the small one-story house set well back from the sidewalk among the clumps of oleanders .
