A Private Cathedral is the most recent (2020) in the Dave Robicheaux series by James Lee Burke. It is on sale at Kindle UK for £0.99 as part of today's Daily Deal. If things go as they usually do, this won't be on sale in the US for a while still, and when it does go on sale it will be for $2.99 or $3.99, so if you want it, I'd grab it now if you can.

Isolde and Johnny - the star-crossed teenage heirs to New Iberia's criminal empires - have run away together, and Robicheaux is tasked with finding them.

In order to rescue the young lovers, and save himself, Robicheaux must face a terrifying time-traveling superhuman hitman capable of inflicting horrifying hallucinations on his victims, and overcome the demons that have tormented him his whole life...
