Another book from the office book exchange shelves that has been collecting dust on my TBR shelves for far too long. This was a serviceable thriller that was a blast from the past due to its 1980 publication date. I love the espionage conducted over pay telephones! The relatively recent movie was obviously updated in this technology as well as the overall plot, which follows the book in a broad sense only.
In doing some research about this book, I discovered that the awesome Golden Earring song "Twilight Zone" was based on this book - I suppose I could have figured that out had I read the book back in the day when it was first published.
