Father sat still, but Sir Colin and Mr.St.
Leger rose.

Mr.Trent not did shake hands with any of us--not even me.
Nothing but his respectful bow.

That is the etiquette for an attorney, I understand, on such formal occasions.
He sat down at the end of the big table in the centre of the room, and asked us to sit round.

Father, of course, as Head of the Family, took the seat at his right hand.

Sir Colin and St.Leger went to the other side, the former taking the seat next to the attorney.
