When questioned for the reason, he replied that at the time Miss Lucas was standing at the window looking down the street. He had called to her, and the din was so great he was compelled to raise the pitch of his voice and call three times before she heard him. Miss Lucas then remembered the circumstance, but was not aware of any unusual noise at the time. There might have been such a noise, however, but her attention was wholly engrossed just then by something else. “What was it that interested you so much?” asked Nick. “Something you saw in the street?” “No, something I saw in a window across the street.” “What did you see?” “A woman.” “Why did the woman prove so interesting?” “Because from her actions I thought she was watching something which was going on in this building.” “Ah! now we are getting at something important. What made you believe she was watching this building?” “Because when she first came to that window she looked out boldly, fearlessly and carelessly; suddenly she drew back and hid her face behind the edge of the window, seemingly on the watch and anxious not to be noticed herself.” “Well?” “She sat thus probably five minutes. Then, springing to her feet, she almost ran away from the window and disappeared.” “What window was it through which she looked?” Miss Lucas pointed directly across the street and answered: “That one.” She had designated the window which Nick had previously noticed to be on a line with the open window of Redway’s private office and the desk of the dead girl. Miss Lucas supplemented her information by saying: “Our offices are directly above these, and I was looking down at the woman--or rather at the place from which she had disappeared a minute before when Mr. Grote called me.” “Could you see the woman’s features?” “Distinctly when she first came to the window.” “Had you ever seen her before?” “Only once.” “When?” “To-day--this afternoon as I was going out to lunch.” “Where was she?” “She got into the elevator as I got out.” “What time was that?” “About half-past two o’clock.” Nick had no doubt that the woman at the window was Redway’s mysterious visitor. Mr. Kennedy and Miss Lucas were dismissed with a caution to repeat none of their information to any one else. Nick requested Mr. Grote to remain a few minutes. After Kennedy and the typewriter had gone back to the private office Nick whispered to the coroner: “Make a pretense of trying to get some further information from Grote, just to keep up the hum of conversation, while I take a look in the private office of Mr. Byke.” So, while the coroner engaged Mr. Grote in further conversation, Nick silently used his pick-lock, entered the private office of Mr. Byke and remained for nearly ten minutes. When he returned to Redway’s office he locked the communicating door behind him, and then said:
