Ruthven remained standing.
"This--this thing," began Ruthven in a voice made husky and indistinct through fury, "this ruffianly behaviour amounts to assault." "As you choose," nodded Selwyn, almost listlessly, "but be quiet; I've something to think of besides your convenience." For a few moments he sat silent, thoughtful, narrowing eyes considering the patterns on the rug at his feet; and Ruthven, weak with rage and apprehension, was forced to stand there awaiting the pleasure of a man of whom he had suddenly become horribly afraid.
