"No matter—I—but go on with your story."
"Owing partly to the mystery which surrounded her birth and gave rise to all sorts of rumours, and partly to her own personality, the gentry of the neighbourhood made quite a pet of her. As a child she was asked occasionally to play with the Squire's crippled daughter and later she used to go to the Hall three times a week to read aloud to her. So, notwithstanding the vicar's good intentions, she grew up to be neither 'fish, flesh, fowl, nor good red herring.' Now all went well till about a year ago, when the Squire's eldest son returned home and fell in love with her. His people naturally opposed the match and, as he is entirely dependent upon them, there seemed no possibility of his marrying her. The girl appeared broken-hearted, and when she came to the castle, every one, the vicar included, thought the affair at an end. I am sure, however, that such was not the case, for as no one at the vicarage wrote to her daily, the letters she received must have come from her young man. Furthermore, she told the servants that she had a cousin in Newhaven, but as she has not a relative in the world, this is obviously a falsehood. Who, then, is this mysterious person she visited? It seems to me almost certain that it was her lover."
"Possibly," agreed Cyril. "But I don't quite see what you are trying to prove by all this. If Prentice did not help her Ladyship to escape, who did?"
"I have not said that Prentice is not a factor in the case, only I believe her part to have been a very subordinate one. Of one thing, however, I am sure, and that is that she did not return to Geralton on the night of the murder."
"How can you be sure of that?" demanded Cyril.
"Because she asked for permission early in the morning to spend the night in Newhaven and had already left the castle before the doctors' visit terminated. Now, although I think it probable that her Ladyship may for a long time have entertained the idea of leaving Geralton, yet I believe that it was the doctors' visit that gave the necessary impetus to convert her idle longing into definite action. Therefore I conclude that Prentice could have had no knowledge of her mistress's sudden flight."
"But how can you know that the whole thing had not been carefully premeditated?"
"Because her Ladyship showed such agitation and distress at hearing the doctors' verdict. If her plans for leaving the castle had been completed, she would have accepted the situation more calmly."
"Has nothing been heard of these doctors?"
"Nothing. We have been able to trace them only as far as London. They could not have been reputable physicians or they would have answered our advertisements, and so I am inclined to believe that you were right and that it was his Lordship who spread the rumours of her Ladyship's insanity."
