On their return to England in September, Shelley took a cottage at Great
Marlow on the Thames, in order to be near his friend Peacock. While it
was being prepared for the reception of his family, he stayed at Bath,
and there heard of Harriet's suicide. The life that once was dearest to
him, had ended thus in misery, desertion, want. The mother of his two
children, abandoned by both her husband and her lover, and driven from
her father's home, had drowned herself after a brief struggle with
circumstance. However Shelley may have felt that his conscience was free
from blame, however small an element of self-reproach may have mingled
with his grief and horror, there is no doubt that he suffered most
acutely. His deepest ground for remorse seems to have been the
conviction that he had drawn Harriet into a sphere of thought and
feeling for which she was not qualified, and that had it not been for
him and his opinions, she might have lived a happy woman in some common
walk of life. One of his biographers asserts that "he continued to be
haunted by certain recollections, partly real and partly imaginative,
which pursued him like an Orestes," and even Trelawny, who knew him only
in the last months of his life, said that the impression of that
dreadful moment was still vivid. We may trace the echo of his feelings
in some painfully pathetic verses written in 1817 (Forman, 3 148.); and
though he did not often speak of Harriet, Peacock has recorded one
memorable occasion on which he disclosed the anguish of his spirit to a
friend. (Fraser, January, 1860, page 102.)

Shelley hurried at once to London, and found some consolation in the
society of Leigh Hunt. The friendship extended to him by that excellent
man at this season of his trouble may perhaps count for something with
those who are inclined to judge him harshly. Two important events
followed immediately upon the tragedy. The first was Shelley's marriage
with Mary Godwin on the 30th of December, 1816. Whether Shelley would
have taken this step except under strong pressure from without, appears
to me very doubtful. Of all men who ever lived, he was the most
resolutely bent on confirming his theories by his practice; and in this
instance there was no valid reason why he should not act up to
principles professed in common by himself and the partner of his
fortunes, no less than by her father and mother. It is, therefore,
reasonable to suppose
