I saw George St. Mabyn start to his feet, his lips livid, while Norah
Blackwater gave a cry which was not far removed from a scream.

'Perhaps I ought to have told this in a different way,' went on my friend. 'Perhaps, directly my memory came back to me, and the events of the past became clear again, I ought to have sought out George St. Mabyn, and especially Colonel Springfield, and told them privately what I know. However, I have thought a good deal before speaking, and—and as this is a family party, I have adopted this method.'

'Why should you tell Colonel Springfield?' and George St. Mabyn seemed to be speaking against his will.

'Because he is most deeply implicated, and because he will have most to explain.'

I heard Springfield laugh at this, a laugh half of derision, half of anger.

'I am afraid,' he said quietly, 'that although we have all congratulated Lord and Lady Carbis on the return of their son, that his loss of memory has disturbed his mental equilibrium in other ways.'

'Oh, no,' said Jack quietly, 'I am quite sane. No doubt it would simplify your course of action very much if I were not, but as a matter of fact my mind was never clearer. My father and mother will tell you that I was never given to hysterics, and I am no great hand at imagination.'

'But—but if you have—have proof of this,'—it was George St. Mabyn who spoke, and his voice was hoarse and unnatural,—'why—why'——? by heaven, it's monstrous!'

Springfield laughed like one amused.

'I do not wish to wound any one's feelings,' he said, 'but I suppose many madmen think they are sane. Of course we sympathize with Lord and Lady Carbis, but I am afraid there is only one conclusion that we can come to. Only on the night when his father and mother came here, before this marvellous change in his memory took place, he said something similar to this, and—and of course we can only regard it as the hallucination of an unbalanced mind. Let us hope after a few months' quiet, things will be normal again.'
