At first, the old feeling that it would be disloyal to Mrs.Goddard even to hint to Mr.Ambrose that he was acquainted with her story withheld him from pursuing such a course.

But as he turned the matter over in his mind it seemed to him that since it was directly for her good, he would now be justified in speaking.

He liked the vicar and he trusted him.

He knew that the vicar had been a good friend to Mrs.Goddard and that he would stand by her in any difficulty so far as he might be able.

The real question was how to make sure that the vicar should not tell his wife.
