Deranged in example sentence
By the time we observe Monica Dolan (in a truly genius bit of casting) delightfully goofing it up as Cora early on we're already hooked, but it is only later on when she reveals herself in her marvellous screen creation, that deranged, scheming, maleficent queen of murder and deceit posing in the guise of the uptight Miss Gilchrist, that she not only effortlessly steals the entire telemovie for herself but quite simply blows off screen anyone who comes near her, including the ever well measured David Suchet who himself seems to be somewhat bedazzled by her acting talents and, very gentlemanly, allows her to take centre stage.
