I've lost interest - though this is, I think, a little better than Havana Blue, Padura's characters are finally somewhat artificial and stilted. And plot is not usually enough to carry a book all by itself. The prose can be good, but it is not overwhelming. And so it's simply not worth the effort. Maybe if I had slept better last night, I'd have more patience this morning. But I did not and do not.
Other, less indolent readers, should not be deterred, however... It's me, not him.
