Query: Quality of the series is not holding up

I have been a big Lawrence Block/Matt Scudder fan and have often recommended books from the series to friends. However, I find that beginning with the previous book in the series, A Long Line of Dead Men, the fun has left the the Scudder books as they become mostly talk and very little action. I still would highly recommend all previous Scudder books -- of which there are 11, but it's time for Block to put this PI to sleep. Now that Scudder has become a permanently sober, legitimate P.I., and stick-in-the mud married middle-aged gum shoe, he is BORING.
