This is a Peter Diamond that somehow escaped me when I discovered and embraced this prickly, irascible detective. If you enjoy the Dalziel and Pascoe novels of Reginald Hill, you'll probably like this series as well.
Diamond has resigned from his Bath CID in a huff and, as this book begins, he is repenting at leisure. That changes when he is hauled back to Bath to deal with John Mountjoy, a woman-abusing escaped prison inmate who has kidnapped a CID officer's daughter and is asking for Diamond. A note: the account of Mountjoy's escape from prison is just brilliant.
Mountjoy claims innocence, even though he was convicted of murder. He wants Diamond, the original arresting officer, to reinvestigate. While the CID plays along to try to keep the daughter alive, Diamond digs in and, with the assistance of the sensible and capable Julie Hargreaves, begins to look at the murder investigation again with what he hopes are fresh eyes. And there are things to see with those fresh eyes.
It is a fairly straightforward journey toward the culmination of this reinvestigation and enough fears about the survival of the kidnapped daughter to keep the tension flowing, but some annoying coincidences keep this from being a flawless Diamond. Even so, I feel this was a worthwhile read to be recommended.
