He had been apprised that the final hour was Three，and he knew he would be summoned some time earlier. inasmuch as the tumbrils jolted heavily and slowly through the streets.Therefore，he resolved to keep Two before his mind，as the hour，and so to strengthen himself in the interval that he might be able，after that time.to strengthen others.
Walking regularly to and fro with his arms folded on his breast，a very different man from the prisoner，who had walked to and fro at La Force，he heard One struck away from him，without surprise. The hour had measured like most other hours.Devoutly thankful to Heaven for his recovered self-possession，he thought，'There is but another now，'and turned to walk again.
Footsteps in the stone passage outside the door. He stopped.
The key was put in the lock，and turned. Before the door was opened，or as it opened，a man said in a low voice，in English：'He has never seen me here；I have kept out of his way.Go you in alone；I wait near.Lose no time！'
The door was quickly opened and closed，and there stood before him face to face，quiet，intent upon him，with the light of a smile on his features，and a cautionary finger on his lip，Sydney Carton.
There was something so bright and remarkable in his look，that，for the moment，the prisoner misdoubted him to be an apparition of his own imagining. But，he spoke，and it was his voice；he tookthe prisoner's hand，and it was his real grasp.
'Of all the people upon earth，you least expected to see me？'he said.
'I could not believe it to be you. I can scarcely believe it now.You are not'—the apprehension came suddenly into his mind—'a prisoner？'
'No. I am accidentally possessed of a power over one of the keepers here，and in virtue of it I stand before you.I come from her—your wife，dear Darnay.'
The prisoner wrung his hand.
'I bring you a request from her.'
'What is it？'
'A most earnest，pressing，and emphatic entreaty，addressed to you in the most pathetic tones of the voice so dear to you，that you well remember.'
The prisoner turned his face partly aside.
'You have no time to ask me why I bring it，or what it means；I have no time to tell you. You must comply with it—take off those boots you wear，and draw on these of mine.'
There was a chair against the wall of the cell，behind the prisoner. Carton，pressing forward，had already，with the speed of lightning，got him down into it，and stood over him，barefoot.
'Draw on these boots of mine. Put your hands to them；put your will to them.Quick！'
'Carton，there is no escaping from this place；it never can be done. You will only die with me.It is madness.'
'It would be madness if I asked you to escape；but do I？When I ask you to pass out at that door，tell me it is madness and remain here. Change that cravat for this of mine，that coat for this of mine.While you do it.let me take this ribbon from your hair，and shake out your hair like this of mine！'
With wonderful quickness，and with a strength both of will and action，that appeared quite supernatural，he forced all these changes upon him. The prisoner was like a young child in his hands.
'Carton！Dear Carton！It is madness. It cannot be accomplished，it never can be done，it has been attempted，and has always failed.I implore you not to add your death to the bitterness of mine.'
'Do I ask you，my dear Darnay，to pass the door？When I ask that，refuse. There are pen and ink and paper on this table.Is your hand steady enough to write？'
'It was when you came in.'
'Steady it again，and write what I shall dictate. Quick，friend，quick！'
Pressing his hand to his bewildered head，Darnay sat down at the table. Carton，with his right hand in his breast，stood close beside him.
'Write exactly as I speak.'
'To whom do I address it？'
'To no one.'Carton still had his hand in his breast.
'Do I date it？'
'No.'
The prisoner looked up，at each question. Carton standing over him with his hand in his breast，looked down.
'f you remember，'said Carton，dictating，'the words that passed between us，long ago，you will readily comprehend this when you see it. You do remember them，I know.It is not in yournature to forget them.'He was drawing his hand from his breast；the prisoner chancing to look up in his hurried wonder as he wrote，the hand stopped，closing upon something.
'Have you written'forget them'？'Carton asked.
'I have. Is that a weapon in your hand？'
'No；I am not armed.'
'What is it in your hand？'
'You shall know directly. Write on；there are but a few words more.'He dictated again.'I am thankful that the time has come，when I can prove them.That I do so is no subject for regret or grief.'As he said these words with his eyes fixed on the writer，his hand slowly and softly moved down close to the writer's face.
The pen dropped from Darnay's fingers on the table，and he looked about him vacantly.
'What vapour is that？'he asked.
'Vapour？'
'Something that crossed me？'
'I am conscious of nothing；there can be nothing here. Take up the pen and finish.Hurry，hurry！'
As if his memory were impaired，or his faculties disordered，the prisoner made an effort to rally his attention. As he looked at Carton with clouded eyes and with an altered manner of breathing，Carton—his hand again in his breast—looked steadily at him.
'Hurry，hurry！'
The prisoner bent over the paper，once more.
'If it had been otherwise'；Carton's hand was again watchfully and softly stealing down；'I never should have used the longer opportunity. If it had been otherwise'；the hand was at theprisoner's face；'I should but have had so much the more to answer for.If it had been otherwise—，'Carton looked at the pen and saw it was trailing off into unintelligible signs.
Carton's hand moved back to his breast no more. The prisoner sprang up with a reproachful look，but Carton's hand was close and firm to his nostrils，and Carton's left arm caught him round the waist.For a few seconds he faintly struggled with the man who had come to lay down his life for him；but，within a minute or so，he was stretched insensible on the ground.
