For her own part, she did not think that a continued residence in Italy would suit her health; the sudden changes of temperature tried her, and people said that the airs rising in the evening from the bay were unwholesome.
Then we received a letter from her which much alarmed us.

It was written from Naples and dated October 25.

John, she said, had been ailing of late with nervousness and insomnia.

On Wednesday, two days before the date of her letter, he had suffered all day from a strange restlessness, which increased after they had retired for the evening.

He could not sleep and had dressed again, telling her he would walk a little in the night air to compose himself.
