I read a fair bit of crime fiction. It’s rare that it diverges from the usual formula. Mark Billingham has achieved this in “good as dead”.
He takes a rather unusual set-up of placing a time limit on the process by giving us a hostage situation created when a shopkeeper produces a gun and holds two members of the public to ransom. His reasons for this lie in the prosecution of his son for knife crime. The subsequent death of his son is what drives the shopkeeper to take matters into his own hands.
Here we have Tom Thorne investigating this death and in my opinion it really works as a premise. The writing is tight, but there was a sloppy error of detail in regard of the manner of the death by a particular drug. This was a small error and can be largely overlooked.
It gets my thumbs up!
