Margie (or Mandy in the reprint) Hayman and Molly Lentham were joint partners in a riding school which they had opened at Hunter Green’s Stables, in the Cotswold village of Mountly. Their school had come into direct competition with a nearby Riding Academy, a very grand establishment run by Miss Lila Williams who had been involved in several attempts to make the girls close down.
