This is one of the three superb long novels Murdoch published in the second half of the 80s. The characters are brilliantly drawn, especially the psychiatrist Thomas, his friend the ambitious, talented but frustrated Harry Cuno, and Harry's son Stuart, the good apprentice of the title. Underneath the typical Murdochian plot twists, the novel tackles profound themes, including depression and mental illness, guilt and forgiveness, and the impact of technology on human relations. The parts of the novel set in London are stronger than those set in the country. Her genius is fully on display here.
