The chance to spend a night ghost-hunting alone with Hudson Holmes at Brambleberry Manor seems like a dream come true for Ruby Watkiss. Maybe, she thinks, this is their chance to get closer. But when mysterious goings-on start happening which have nothing to do with the spirit world, the pair are catapulted off on another sleuthing adventure. And as the snow starts to fall and emotions are rising at the Little Duck Pond Cafe, Ruby is faced with a double challenge. Can she be braver than she's ever been, in order to rescue something very close to her heart? And can she convince a distinctly 'bah-humbug' Hudson that Christmas really can be the most wonderful time of the year?
