"I'll 'phone my office," said Drew hurriedly as steps were heard in the hall. "I'll get up five operatives--no, six--right away. This all may be a hoax, but I've lived forty-one years too long to overlook a threat of this kind. Particularly when it concerns a man who has made as many enemies as you have." The butler parted the portières as Drew ceased speaking. Stockbridge nodded and indicated that the detective wanted to go downstairs. The butler led the way to the lower telephone. Into this, Drew spoke hurriedly and very much to the point. He secured three numbers in rapid succession. He snapped his orders in a manner to set the cut-glass tinkling on the pantry shelves. He hung up the receiver, glanced shrewdly at the servants about, then climbed the stairs like a boy of twelve. "All is set!" he announced to Stockbridge as he entered the library and crossed to the table. "All moving, now! My wire-chief had gone home. I got the chief operator. She's going to send the first trouble-man handy. Delaney will be up from the office with his flying squad. I left it to him to arrange about tracing the call through a telephone official. No use telling the chief operator too much. The official will go right over her head and into the heart of the thing. Now,"--Drew pulled down the lapels of his black coat and leaned over the Magnate. "Now," he said with vigor, "now, what about your servants? I had a good look at some of them. How about that English butler? How long have you had him?" "Ten years! Brought him over, myself. Wife picked the other servants. They're all old, tried and trusted. I'll answer for them. She died telling me to take care of them. I don't think her equal lived in choosing help. It was uncanny!" Drew stroked his cropped mustache. "Good!" he said. "That's fine! We'll start with the supposition that they're _not_ guilty. Are any of them of German birth?" "My valet is part German, but he ran away to avoid their army. He hates the Junker party. Says 'It is responsible for the War.'" "How long have you had him?" "Nine years." "That should let him out. Well," Drew added with a sweeping glance about the library, "well, these big windows--how about them?" The detective advanced to the front of the room as he asked the question. "Two," he mused. "Two bay-windows of the superior order. Curtains very heavy and rich. There's a good catch on this one," he added springing upon the radiator-box. "And a good catch on this one. Both catches are closed. Seem to have been closed for some time. Here's dust. High-class housekeeper, but I've got her here." Drew smiled as he ran his fingers over the upper sash. He peered out into the Avenue with its flowing tide of vehicles. He turned and said to Stockbridge: "Suppose you order your butler or doorman to shut the outside blinds. It's getting dark and cold. I want to be sure that no one can get through this way."
