The dead cluster around Thomas Cromwell in this darkly magnificent sequel to “Wolf Hall.” He keeps them with him, giving the names of his beloved wife and daughters to the falcons he flies with his king, Henry VIII, and nursing memories of his disgraced mentor, Cardinal Wolsey, whose persecutors will soon suffer Cromwell’s vengeance. Deceased enemies also linger in his thoughts: He’s forced to reconsider his hatred for his brutal father, and he can’t seem to dismiss Thomas More, whom he maneuvered to execution in 1535. More’s bitter aphorisms resurface to remind Cromwell of the dangerous path he has chosen in serving Henry’s capricious royal will.
