At her feet. — Literally, between her feet, as though the dauntless woman had stridden over him as he lay in the dead sleep of weariness.
He bowed. — The word means that he suddenly curled up his knees in one contortion of agony.
He fell. — Rolling, perhaps, off the divan on which he was resting.
He lay down. — Motionless in death, after that one convulsive movement.
Dead. — Rather, slaughtered, or murdered. With this one terrific word the scene ends, as with a blow.
