"When I showed him into his bedroom and loaned him a pair of pajamas." "Did you help him undress?" "No, as he assured me, with drunken gravity, that he could manage it himself." "Did you inform your wife and daughter that Mr. Spencer was spending the night in your house?" "No. My wife was downstairs entertaining her guests, and my daughter was asleep in her room. I did not see either of them until the next morning." "Where did you go after leaving Mr. Spencer in his bedroom?" "To my studio in the attic. I remained there all night absorbed in my work." "Did you hear any unusual sounds during the night?" "No; my studio, or workshop, is sound-proof. And it is the same throughout the house," he added. "The walls, besides being of unusual width, were all deadened by my grandfather's direction. He had a horror of noise." "When did you leave your studio?" "About seven o'clock Wednesday morning." "Did you use the elevator then?" "No, I seldom use it." Whitney twisted about in his chair. "I had the elevator installed for the convenience of my wife and daughter." Penfield made an entry in his notebook, then faced Whitney directly. "Have you in connection with your workshop a photographic outfit and darkroom?" he asked. "I have." "I am told that you are working on a sort of camera which, used in an aeroplane, makes a map of the country over which the machine passes. Is that correct, Mr. Whitney?" "Yes," acknowledged Whitney. "A patent is pending." "Had it gotten about among your servants that you were working upon an important invention?" "It's very possible," Whitney conceded. "Did Julie, your wife's maid, ever evince undue curiosity in your work?" Whitney wrinkled his brow in thought. "No," he said. "I can't say that I am aware she did. When I go to my studio, as we usually call my workshop, it is an understood thing that I am not to be disturbed by _anyone_. It is a rule I enforce by dismissal if broken, and the servants have learned by experience to obey." "Has your household access to your studio when you are not there?" "No, I securely lock the door whenever I leave the room." "Are you ever joined while in your studio by your wife and daughter and their friends?" "Occasionally they bring Miss Grey and Senator Foster in to see my models." "Did you confide the particulars of your latest invention to Mr. Spencer?" "I did not." "Did he ever show deep interest in it?" "Only questioned me about it now and then," replied Whitney casually, and Charles Miller alone noted the nervous twitching of his eyelids. "Was the electric light turned on in Mr. Spencer's room when you left him for the night?" "Y-yes." Whitney reflected for a moment, then added, "I believe the bulb by the bureau was burning, but I can't swear to it." "Did Mr. Spencer give you any inkling Tuesday night that he intended to be an early riser on Wednesday morning?" "No, he never mentioned the subject."
