‘My poor fellow, I hated to take such a step; but it was really necessary for your own safety. You are a man, and a brave one. Won’t you listen to me for a few minutes? When you have heard what I have to say I shall release you. In the meantime I apologise for the outrage, as I dare say you consider it!’ Harold was reasonable; and he was now blind and helpless. Moreover, there was something in the Doctor’s voice that carried a sense of power with it.

‘Go on! I shall listen!’ He compelled himself to quietude. The Doctor saw, and realised that he was master of himself. There were some snips of scissors, and he was free.

‘See! all I want is calm for a short time, and you have it. May I go on?’

‘Go on!’ said Harold, not without respect. The Doctor after a pause spoke:

‘My poor fellow, I want you to understand that I wish to help you, to do all in my power to restore to you that which you seem to have lost! I can sympathise with your desire to quit life altogether now that the best part of it, sight, seems gone. I do not pretend to judge the actions of my fellows; and if you determine to carry out your purpose I shall not be able to prevent you for ever. I shall not try to. But you certainly shall not do so till you know what I know! I had wished to wait till I could be a little more certain before I took you into confidence with regard to my guessing as to the future. But your desire to destroy yourself forces my hand. Now let me tell you that there is a possibility of the removal of the cause of your purpose.’

‘What do you mean?’ gasped Harold. He was afraid to think outright and to the full what the other’s words seemed to imply.

‘I mean,’ said the other solemnly, ‘that there is a possibility, more than a possibility, that you may recover your sight!’ As he spoke there was a little break in his voice. He too was somewhat unnerved at the situation.

Harold lay still. The whole universe seemed to sway, and then whirl round him in chaotic mass. Through it at length he seemed to hear the calm voice:

‘At first I could not be sure of my surmise, for when I used the ophthalmoscope your suffering was too recent to disclose the cause I looked for. Now I am fairly sure of it. What I have since heard from you has convinced me; your having suffered from rheumatic fever, and the recrudescence of the rheumatic pain after your terrible experience of the fire and that long chilling swim with so seemingly hopeless an end to it; the symptoms which I have since noticed, though they have not been as enlightening to me as they might be. Your disease, as I have diagnosed it, is an obscure one and not common. I have not before been able to study a case. All these things give me great hopes.’

‘Thank God! Thank God!’ the voice from the bed was now a whisper.
