“That’s enough of pantomime,” it said, with a peculiar note of cruel, triumphant command. “Now give us your confession from ‘The Daughters of Men’--give it, but remember that you are not a great actress, that you are so bad that you would be hooted from the cheapest stage. Remember that you are ugly and dressed in rags, that you are awkward and ungainly in your movements, that your voice is like a file. Remember it not only now, but always. You will never be able to act. Your acting is a nightmare, and you are a fright--when you aren’t a joke. But show us what you can do in that confession scene.” Nick and Chick grew tense as they listened to those unbelievable words, and to the heartless chuckles and whisperings with which they were received. Apparently there were several men in the “audience”--probably Chester and some of Grantley’s other former accomplices. The meaning was plain--all too plain. The proud, beautiful Helga Lund was once more under hypnotic influence, and Grantley, with devilish ingenuity, was impressing suggestions upon her poor, tortured brain, suggestions which were designed to rob her of her great ability, not only for the moment, but, unless their baneful effect could be removed, for all the rest of her life. She, who had earned the plaudits of royalty in most of the countries of Europe, was being made a show of for the amusement of a handful of ruthless scoffers. It made the detectives’ blood boil in their veins and their hands clench until their knuckles were white, but they managed somehow to keep from betraying themselves. The employment of hypnotism in such a way was plainly within the scope of the new law against unwarranted operations or experiments on human beings, without their consent; but it was necessary to secure as much evidence as possible before interfering. To that end Nick Carter took out of a pocket case a curious little instrument, which he was in the habit of calling his “keyhole periscope.” It consisted of a small black tube, about the length and diameter of a lead pencil. There was an eyepiece at one end. At the other a semicircular lens bulged out. It was designed to serve the same purpose as the periscope of a submarine torpedo boat--that is, to give a view on all sides of a given area at once. The exposed convex lens, when thrust through a keyhole or other small aperture, received images of objects from every angle in the room beyond, and magnified them, in just the same way as the similarly constructed periscope of a submarine projects above the level of the water and gives those in the submerged vessel below a view of all objects on the surface, within a wide radius. Nick had noted that there was no key in the lock of the door. Taking advantage of that fact, he crept silently forward, inserted the wonderful little instrument in the round upper portion of the hole, and, stooping, applied his eye to the eyepiece.
