Query: Lawrence Block wrote this?

I have all the Matt Scudder stories, all of the Burglar books, and a number of other books by Block. He is one of the greatest writers of our time, in my opinion. That is why I simply can't believe he wrote Random Walk. I read it some years ago, but it remains in my memory as one of the *stupidest* stories I ever read. Mercifully, it is out of print now, and let's just hope it stays that way. Guess this book just illustrates that even the best writers have their off times.
