Clever Beatrice and the Best Little Pony

Someone has been running the heroine's pony ragged at night in Clever Beatrice and the Best Little Pony by Margaret Willey, illus. by Heather Solomon. So she consults Monsieur Le Pain (his shingle reads ""Fresh Bread & All Things Not Easily Explained""), who blames it on a lutin (a ""little bearded [man]... from the old country"") and the duo sets out to outwit it. .
