I picked up this book after having read its second installment (The Road to Omaha) first. I found that novel to be witty and humorous, so I naturally expected quite as much from its predecessor. I was left disappointed. Not a single time this book made me even grin. All of the humor in it is severely dated, and the way every woman is overly sexualized all throughout the book is tiring, granted it may be my fault for reading it 45 years after it was published, but a good joke should remain funny, forty years ago or in the present day. Characters were average, none of them had any real personalities outside of the two protagonists, Mackenzie Hawkins and Sam Devereaux, who was exceptionally whiny and insufferable the entirety of the time he appeared.
There's not much to be said about the plot, A U.S military hero fallen in disgrace wants to kidnap the Pope, which he does, and then... nothing happens. The climax of the story is, in my opinion, poorly placed, as it dies down quickly and disappointingly when it should be at its peak.
In the end, even if it seems I'm being too harsh on Ludlum, it's an entertaining book that was never meant to be a masterpiece, It didn't hold well to the pass of time but I can't judge it as if had read it 45 years ago. 2/5.
