‘Let go!’ said Riderhood. ‘Stop! What are you trying at? You can’t drown Me. Ain’t I told you that the man as has come through drowning can never be drowned? I can’t be drowned.’ ‘I can be!’ returned Bradley, in a desperate, clenched voice. ‘I am resolved to be. I’ll hold you living, and I’ll hold you dead. Come down!’ Riderhood went over into the smooth pit, backward, and Bradley Headstone upon him. When the two were found, lying under the ooze and scum behind one of the rotting gates, Riderhood’s hold had relaxed, probably in falling, and his eyes were staring upward. But, he was girdled still with Bradley’s iron ring, and the rivets of the iron ring held tight.
The beginning of this dialogue had me on the edge of my seat. I knew that this time the blackmail between these two couldn't last long, given that the book is almost coming to an end. But I certainly was not expecting for the both of them to end up dead by drowning together. I think Dickens was very poetic in the demise of these two men.
