The allusions to his unknown mother that had been made by Lady Merthyr Tydvil, and the cropping-up of the same subject during St Aubyn's visit, had somehow connected themselves in his mind with the mysterious appearance of the strange lady at the garden gate on the evening of the tea-party at the vicarage.

Lady Merthyr Tydvil had recognised a strong resemblance between his mother as she had known her and himself, and he had noticed the very same thing in the strange lady.

There were the same dark eyes, the same long, pale face, even (as far as he could judge) the same shade in colour of the hair.
He would have thought little or nothing of this had it not been for the inexplicable and almost miraculous vanishing of the figure when there was absolutely nowhere for it to vanish to.

Austin knew nothing of such happenings; with all his reading he had never chanced to open a single book that dealt with phenomena of this class, much less any written by scientific and sober investigators, so that the entire subject was an undiscovered country to him.

Had he done so, his perplexity would not have been nearly so great, and very probably he might have recognised the fact of his own remarkable psychic powers.
Still, in spite of this disadvantage, the conviction was slowly but surely forcing itself upon his mind that the lady he had seen was no one but his own mother.
