Becoming Inspector Chen (An Inspector Chen mystery, 11)

Inspector Chen is excluded from a poetry case as he awaits possible disciplinary action, leaving him to reflect on his career . . . but does his past hold a clue to the poetry case?
After a number of grueling cases Chief Inspector Chen is facing mounting pressure from his superiors, many of whom are concerned with where his loyalties lie. What's more, he is excluded from an investigation into an incendiary poem posted on an online forum.
Wracked with self-doubt and facing an anxious wait to discover the fate of his career, Chen is left to reflect on the events that have led to where he is now - from his amateur investigations as a child during the Cultural Revolution, to his very first case on the Shanghai Police Force.
Has fighting for the Chinese people and the morals he believes in put him in conflict with the Party? Why is he being kept away from the new case? As well as his career, is his life now also at risk?
