Margaret, as she uttered the word, was conscious of a catching in her breath; she herself did not know why.
"Mrs. Gregory Lamb is the woman I found by the roadside; who told me that her name was Isabel Burney; who called herself Mrs. Cuthbert Grahame; who juggled into existence the will under which she inherits; who murdered the man out of whom she got it by a trick."
Margaret was silent, curiously silent. Then she drew a long breath, and she said--
"Now I understand".
The doctor was struck by something in her intonation which was odd.
"Just what is it you understand?"
She repeated her own words.
"Now I understand. The veil which seemed to obscure my sight is being torn away; things are getting plainer and plainer. She was not mad, as we thought; it was we who were ignorant. Doctor, I believe that the finger of God, of which you spoke just now, has moved already."
"It is likely. It is some time since I looked for it to move, but He chooses His own time. As for what you say about your understanding, to me your words are cryptic--unriddle them, young lady, if you please."
Margaret, in her turn, told her tale: of her visit to Mrs. Gregory Lamb; of its abrupt and singular termination. The doctor listened with every sign of the liveliest interest.
