Ross H. Spencer started writing late in life, but when he started, he wrote fast and he wrote a lot. His first series was about a p. i. named Chance Perdue, and the first book in that series was The Dada Caper. I think I can say without fear of contradiction that this series is unique.
Spencer eschewed (I've always wanted to say that) most punctuation, though he did use periods and question marks. All his paragraphs are one sentence long. Each chapter begins with some words of wisdom from the sage known as Monroe D. Underwood. The setting is Chicago, and the plots pretty much don't matter. The intent is humorous, and I think you'll either get it or you won't. I enjoyed every book in the series, but I can see that the style might get a bit wearisome to others. I also found the books very funny, for the most part.
"Tough, Tight-Lipped, Incompetent, Chance Perdue Is One of a Kind and the Kind Women Love."
He said oh flaming Heavenly Father.
I am very good at shrugging.
I can just shrug up a storm.
I said look Mr. Ammson.
I said Williams met this chick in the hotel lounge.
I said he got her looped.
I said he took her upstairs.
I said it looked like just the old routine.
I said how was I to know she was Mrs. Williams?
I said my God I didn't know Mrs. Williams from a side of beef.
And so on. You get the idea.
I highly suggest you read this piece by Mike Resnick about Ross H. Spencer. The man himself was as incredible as his books. If you're a writer or would like to be, or if you're just interested in good stories, check it out.
