Book 6 of the police procedural series featuring DC Smith, the aging cop who refuses to retire. After his wife died, he wants to keep busy and relevant.

After a few weeks off for minor knee surgery, the old man returns — grumpy.

He is feeling his age, both physically and mentally and that he no longer really fits in, even his sense of humour is subdued …

Goodreads

I read these books for Smith’s humour.

Therefore this was the least satisfying of the series, so far. Smith was too grumpy to be amusing.
