Two newcomers are visiting the convent in the hope of joining the nuns. But soon after their arrival, there's a mysterious late-night intruder. Who left the single red rose on the chapel steps? And are they connected to the new-age travellers camping on the moor? When one of the women is found bludgeoned to death, Sister Joan knows that their isolated convent is no longer safe. Teaming up with Detective Sergeant Mill, Sister Joan must once again investigate the grisly goings-on.
