Her hand was on my arm and I felt it suddenly stiffen.
I was not alarmed, but I gave her a quick look and saw that something had happened.

What, I could not at the moment determine.

She didn't answer when I spoke to her and seemed to be mainly concerned in getting out of the church before her emotions overcame her.

This she succeeded in doing with my help; and, once in the vestibule, recovered herself so completely, and met all my inquiries with such a gay shrug of the shoulders, that I should have passed the matter over as a mere attack of nerves, if I had not afterwards detected in her face, through all the hurry and excitement of the ensuing reception, a strained expression not at all natural to her.

This was still more evident after the congratulations of a certain guest, who, I am sure, whispered to her before he passed on; and when the time came for her to go up-stairs she was so pale and unlike herself that I became seriously alarmed and asked if she felt well enough to start upon the journey we had meditated.
Instantly her manner changed.
