I have no idea how I came to own The Lighthouse, by PD James, a charity shop I suspect, but I did, and now it sits on my bookshelf. The first time I read it was in the midst of a clear-out, and I allowed myself to be distracted.

Now, I like murder mysteries, but I have a hard time these days finding the sort I want to read: I’m not so keen on the fast-paced, conspiracy-theory-heavy thrillers, or those that provide every possible detail to prove the writer knows his/her police procedure; but I like Commander Adam Dalgliesh, and I like James’ writing. It is evident, but not in-your-face, that she knows her stuff (and given her working life before writing, she probably ought to).

The Lighthouse is set on a fictional island off the Cornish coast. The sort of mystery with a limited suspect-pool and the murderer can’t get away, but everyone’s cooped up with him/her, so s/he’s likely to get desperate as the detective gets closer to the answer. This particular island is run as a very exclusive get-away for the over-stressed professionals, and they pay for the island’s privacy. And then one dies.

Dalgliesh is a sensible, robust sort of detective. If he lacks the eccentric flair I normally like in my detectives, there is a comforting solidity about him. Having found a much earlier James, from the ’70s, I’ve come to the conclusion that Dalgliesh must be a sort of Peter Pan character, since The Lighthouse is from 2005, but then, I haven’t read all the others to know what happens in his life between then and now, and nor do I know even his approximate age in either novel.

But I enjoyed The Lighthouse, and not once did I think I really must get back to my tidying.
