three o'clock
At about nine o'clock in the evening , Dyce inquired at Rivenoak lodge : he learnt that there was still no change whatever in the patient 's condition ; Dr. Baldwin remained in the house . In spite of his anxious thoughts , Dyce slept particularly well . Immediately after breakfast , he drove again to Rivenoak , and had no sooner alighted from the cab than he saw that the blinds were down at the lodge windows . Lady Ogram , he learnt , had died between two and three o'clock . He dismissed his vehicle , and walked along the roads skirting the wall of the park . Now , indeed , was his life 's critical moment . How long must elapse before he could know the contents of Lady Ogram 's will ?
