"Quite sure, Miss Gray?" and the spinster bridled at his quizzical glance. "I am willing to take my dying oath," she said solemnly, "that I left that room in total darkness." CHAPTER XVII CIRCUMSTANTIAL EVIDENCE "Mr. Winslow Whitney will be the next witness," announced Coroner Penfield, first signifying to Miss Kiametia Grey that her presence was no longer required in the witness chair, and the spinster, with an audible sigh of relief, picked up her gold mesh purse and its dangling accessories and hastily left the room. There was an instant craning of necks and raising of lorgnettes as the door opened to admit Winslow Whitney. Courteously acknowledging the bows of several friends seated near the entrance, he made his way to the witness chair with a firm tread, and his clear voice was plainly heard as, in answer to the morgue master's questions, he stated his full name, age, and length of residence in Washington, having first taken the oath to tell the truth, the whole truth, and nothing but the truth. Charles Miller, watching him intently, was relieved to find that the nervous twitching of the muscles of his face and hands, so noticeable the day before, was missing. Though his haggard face testified to a sleepless night, Whitney was outwardly composed. "For how many years have you known Sinclair Spencer?" asked the coroner. "Fully ten." "Were you intimately acquainted?" "No. I knew him as I know dozens of other men; he was frequently at my house, and on several occasions he assisted me in protecting my patents in the law courts." "But you would not call him an intimate friend?" "Most assuredly not." "Was he in the habit of spending the night in your house?" "He has sometimes stopped with me during the summer months when I was detained in Washington and my wife and daughter were away." "He was familiar with your house, then?" "You mean--architecturally?" "Yes. Could he find his way about it alone in the dark?" "I presume he could--provided he was sober," dryly. "The arrangement of the rooms is not complicated, and one floor is very much like another." Coroner Penfield cleared his throat. "Was Mr. Spencer a welcome guest in your house?" "Certainly; otherwise I should not have invited him," replied Whitney, with quiet dignity. "Let me amend my question." The coroner laid down his pencil. "Was Mr. Spencer on a friendly footing with each member of your household?" "I have every reason to believe he was." "Was Mr. Spencer's manner the same as usual when he called upon you Tuesday evening?" "No." "In what way was it different?" "He had been drinking." "Was he rough, boisterous?" "The latter, yes. So much so, that I suggested he spend the night. I did not wish him to go downstairs and disturb my wife's guests, which he was quite capable of doing had the whim seized him." "Were you then upstairs, Mr. Whitney?" "Yes, in my wife's boudoir on the first bedroom floor." "When did you last see Mr. Spencer alive?"
