The Lifers' Club is written by Francis Pryor, who is a real archaeologist who has written several very good non-fiction books on archaeology - and reading the descriptions of archeological digs here took me right back to the days when I was a circuit digger. Reading about setting up the grid, and dumpy levels (used for surveying), and trowelling back - it was like relaxing into something when you don't even realise you've been tense.
The mystery was interesting and complex as well, involving an "honour killing" in a Turkish family and the Turkish family's links to one of the archaeologists who were working on a dig when the young woman disappeared, who has since done very well for himself and now runs his own company. Our hero, Alan Cadbury, goes to work for the company, and at the same time is trying to prove the innocence of the young man convicted of the murder of his sister, who is a member of the Lifers' Club of the title in the nearby high security prison.
There was an interesting sub-plot about a Victorian pillar of the community who turned out not to be such a nice man after all, thanks to discoveries at a dig in a churchyard, which ties into the main plot when several of the Saxon skeletons they dig up turn out to come from Eastern Europe.
I really enjoyed this one, and will be looking out for the sequel.
