Cold Maiden

Cold Maidens are reasonably powerful Type One ghosts. Their manifestations always appear female, and are usually capable of hovering high above the ground or even flying. They radiate especially cold chill, and almost always are barely visible, even from the corner of your eye, until they decide to swoop at you with startling speed, ectoplasm trailing behind...

They are best dealt with using lavender and/or rapiers, as scattering salt or iron chains doesn't work too well against something ten feet in the air. Anthony Lockwood, Lucy Carlyle, and Flo Bones encounter a pair of Cold Maidens, one of which was a toddler, at the eastern corner of the Thames.
