Pope's mania for suspicion deprives his suggestions of the slightest value.

The only inference to be drawn is, that he drew closer to Martha Blount as years went by; and was anxious that she should become independent of her family.

This naturally led to mutual dislike and suspicion, but nobody can now say whether Teresa pinched her mother, nor what would have been her account of Martha's relations to Pope.
Johnson repeats a story that Martha neglected Pope "with shameful unkindness," in his later years.

It is clearly exaggerated or quite unfounded.

At any rate, the poor sickly man, in his premature and childless old age, looked up to her with fond affection, and left to her nearly the whole of his fortune.
