Estrapade

Then one day she went riding on her favourite horse, Coco, without a helmet, and Kwango, her prize borzoi, leapt out in front of her, causing Coco to perform an estrapade which sent Vivienne flying and falling, landing head first on the concrete drive, killing her instantly.

He did not want to look at the rigid legs, at the feet hanging down nervelessly, with their bare toes some six inches above the floor, to know that the man had been given the estrapade till he had swooned.
