dismay, Juve went on, emphasising each of his words, and with a sardonic smile flickering over his face. "And you, Mademoiselle Jeanne — you are Charles Rambert!"

A Prisoner and a Witness
Juve had spoken in a tone of command that brooked no reply. His keen eyes seemed to pierce through Paul and read his inmost soul. The winking light of the street lamp shed a wan halo round the lad, who obviously wanted to move away from its radius, but Juve held him fast.
"Come now, answer! You are Charles Rambert, and you were Mademoiselle Jeanne?"
"I don't understand," Paul declared.
"Really!" sneered Juve. He hailed a passing cab. "Get in," he ordered briefly, and pushing the lad in before him he gave an address to the driver, entered the cab and shut the door. Juve sat there rubbing his hands as if well pleased with his night's work. For several minutes he remained silent, and then turned to his companion.
"You think it is clever to deny it," he remarked, "but do you imagine it isn't obvious to anyone that you are Charles Rambert, and that you were disguised as Mademoiselle Jeanne?"
"But you are wrong," Paul insisted. "Charles Rambert is dead."
"So you know that, do you? Then you admit that you know whom I am talking about?"
The lad coloured and began to tremble. Juve looked out of the window, pretending not to notice him, and smiled gently. Then he went on in a friendly tone. "But you know it's stupid to deny what can't be denied. Besides, you should remember that if I know you are Charles Rambert I must know something else as well; and therefore —— "
"Well, yes," Paul acknowledged, "I am Charles Rambert, and I was disguised as Mademoiselle Jeanne. How did you know it? Why were you at the Saint-Anthony's Pig? Had you come to arrest me? And where are you taking me now — to prison?"
Juve shrugged his shoulders.
"You want to know too much, my boy. Besides, you ought to know Paris, and so ought to be able to guess where I told the driver to go, merely by looking at the streets we are passing through."
"That is exactly what frightens me," Charles Rambert replied. "We are on the quays, near the Law Courts."
"And the Police Station, my son. Quite so. Now it's quite useless to make a scene: you will gain nothing by attempting to get away. You are in the hands of justice, or rather in my hands, which is not quite the same thing, so come quietly. That is really good advice!"
A few minutes later the cab stopped at the Tour Pointue which has such melancholy associations for so many criminals. Juve alighted and made his companion alight as well, paid the driver, and walked up the staircase to the first floor of the building. It was daylight now, and the men were coming on duty; all of them saluted Juve as he walked along with his trembling captive. The detective went down one long passage, turned into another, and opened a door.
"Go in there," he ordered curtly.
Charles Rambert obeyed, and found himself in a small room the nature of which he recognised immediately from the furniture it contained. It was the measuring room of the anthropometric service. So what he feared was about to happen: Juve was going to lock him up!
But the detective called out in a loud tone: "Hector, please!" and one of the men who remained on duty in the department, in case they were required by any of the detective inspectors to find the records of any previously convicted criminal, came hurrying in.
"Ah, M. Juve, and with a bag too! So early? You think he has been here before?"
"No," said Juve in a dry tone that put a stop to further indiscreet questions. "I don't want you to look up my companion's record, but to take his measurements, and very carefully too."
The man was somewhat surprised at the order, for it was not usual to be asked to do such work at so very early an hour. He was rather irritable too at being disturbed from the rest he was enjoying, and it was very curtly that he spoke to Charles Rambert.
"Come here, please: the standard first: take off your boots."
Charles Rambert obeyed and stood under the standard of measurement, and then, as the assistant ordered him, he submitted to having his fingers smeared with ink so that his finger prints might be taken, to being photographed, full face and in profile, and finally to having the width of his head, from ear to ear, measured with a special pair of caliper compasses.
Hector was surprised by his docility.
"I must say your friend is not very talkative, M. Juve. What has he been up to?" and as the detective merely shrugged his shoulders and did not reply, he went on: "That's done, sir. We will develop the negatives and take the prints, and recopy the measurements, and the record shall be classified in the register in a couple of hours."
Charles Rambert grew momentarily more scared. He felt that he was definitely arrested now. But Juve left the arm-chair in which he had been resting, and coming up to him laid his hand upon his shoulder, speaking the while with a certain gentleness.
"Come: there are some other points as to which I wish to examine you." He led him from the anthropometric room along a dark corridor, and presently taking a key from his pocket, opened a door and pushed the lad in before him. "Go in there," he said. "This is where we make the dynamometer tests."
A layman looking round the room might almost have supposed that it was merely some carpenter's shop. Pieces of wood, of various shapes and sizes and sorts, were arranged along the wall or laid upon the floor; in glass cases were whole heaps of strips of metal, five or six inches long, and of varying thickness.
Juve closed the door carefully behind him.
"For pity's sake, M. Juve, tell me what you are going to do with me," Charles Rambert implored.
The detective smiled.
"Well, there you ask a question which I can't answer off-hand. What am I going to do with you, eh? That still depends upon a good many things."
As he spoke Juve tossed his hat aside and, looking at a rather high kind of little table, proceeded to remove from it a grey cloth which protected it from dust, and drew it into the middle of the room. This article was composed of a metal body screwed on to a strong tripod, with a lower tray that moved backwards and forwards, and two lateral buttresses with a steel cross-piece firmly bolted on to them above. Upon this framework were two dynamometers worked by an ingenious piece of mechanism. Juve looked at Charles Rambert and explained.
"This is Dr. Bertillon's effraction dynamometer. I am going to make use of it to find out at once whether you are or are not deserving of some little interest. I don't want to tell you more just at present." Juve slipped into a specially prepared notch a thin strip of wood, which he had selected with particular care from one of the heaps of material arranged along the wall. From a chest he took a tool which Charles Rambert, who had had some intimate experience of late with the light-fingered community, immediately recognised as a jemmy. "Take hold of that," said Juve, and as Charles took it in his hand he added: "Now put the jemmy into this groove, and press with all your force. If you can move that needle to a point which I know, and which it is difficult but
