Children’s book, enjoyed in ’60’s but probably from ’30’s or 40’s, possibly English. Included a story about young brother and sister in a churchyard (castle yard?), playing with a ball. The brother (possibly named Roland) went to retrieve the ball when it went over a fence, but forgot to go “widdershins” and was taken by a witch. The little girl goes in search of her brother. (It is possible the girl was taken and the boy went to save her, but I remember it as the girl.) Illustrated with sweet old-fashioned colored drawings.
The story “East of the Sun, West of the Moon” may be in the same collection, or may just have been in the same bookcase.
