The Silver Pigs - Lindsey Davis The Silver Pigs is fun to read. And if you're looking to read to relax, there's no better praise.

As I mentioned in my comment, the voice and tone reminded me of Glen Cook's Garrett, P.I. series sans the fantasy element. Even more strongly, I'm reminded of a Roman Rockford Files, which may be brilliantly illuminative to those of a certain age or who have a taste for '70s detective shows. For the rest, you can wiki it and then hunt down copies of the episodes (which stream on Netflix).

But I'm digressing...

Marcus Didius Falco is an ex-legionary, current informer (i.e., private investigator) in the Rome of Vespasian (AD 69-79). If you're looking for fast-paced, engaging and smartly written bedside/airplane reading then I can recommend this series.

Fortunately, my library has all but 3 of the 20 books Davis has written so far. Though, of course, they wouldn't have #2 but my luck continues good as my alternate library has a copy, which I've duly ordered.
