Don't you remember how John O'Neill heard the words 'liar' and 'deceit'?
Percival Brooks had never deceived his father.

His sins were all on the surface.

Murray had led a quiet life, had pandered to his father, and fawned upon him, until, like most hypocrites, he at last got found out.

Who knows what ugly gambling debt or debt of honour, suddenly revealed to old Brooks, was the cause of that last and deadly quarrel?
"You remember that it was Percival who remained beside his father and carried him up to his room.

Where was Murray throughout that long and painful day, when his father lay dying--he, the idolised son, the apple of the old man's eye?
You never hear his name mentioned as being present there all that day.
