Showing A Clear Conscience by Frances Fyfield

Helen West's personal life is in need of repair, and she decides the first move is to tidy up her home, helped by her cleaning lady, Cath, who is trapped in a miserable marriage. Working by day with domestic violence cases, Helen finds it too easy to turn a blind eye to Cath's unhappiness, but then her personal and professional lives collide as she witnesses the destructive forces of love and guilt, and finds herself applying her own version of justice.
