Lonely and forlorn after their mother's death and their sudden arrival at Aunt Mabel's seaside boarding-house, John, Mary and Ben Mallory are unimpressed with their new life in England. But there are wonderful surprises in store for them when they discover a secret way into the grand and empty house next door. Soon all sorts of unexpected events will unfold as the siblings encounter a whole host of eccentric characters and happenings.

This is a lovely adventure story that took me back to my childhood.
It was the ideal book for a day when I was feeling poorly.
