It was only when I caught sight of the red blotch on Mrs.Harker's forehead that I was brought back to reality.

Even now, when I am gravely revolving the matter, it is almost impossible to realize that the cause of all our trouble is still existent.

It is only now and again, when something recalls it to her mind, that she thinks of her terrible scar.

We are to meet here in my study in half an hour and decide on our course of action.
