[I have been reading the Spenser books as a cure for cabin fever and he gets on a Rolling Rock Jag.]
The Spenser books are way more unrealistic than the Philip Marlowe series written by Raymond Chandler. But the pacing is better, even if the Marlowe books are superior, from a literary standpoint. If you want even faster pacing, consider the Elvis Cole series by Robert Crais. It’s current day TV series pacing - real roller coaster stuff.
