He would even call Dolly into his bedroom late at night, bringing her out of bed for the occasion, to discuss with her some point of legal strategy,--of legal but still honest strategy,--which had just occurred to him.

Maybe he had not quite seen his way as to the honesty, and wanted Dolly's opinion on the subject.
Dolly would come in in her dressing-gown, and, sitting on his bed, would discuss the matter with him as advocate against the devil.

Sometimes she would be convinced; more frequently she would hold her own.

But the points which were discussed in that way, and the strength of argumentation which was used on either side, would have surprised the clients, and the partner, and the clerks, and the eloquent barrister who was occasionally employed to support this side or the other.

The eloquent barrister, or it might be the client himself, startled sometimes at the amount of enthusiasm which Mr.Grey would throw into his argument, would little dream that the very words had come from the young lady in her dressing-gown.
