I am currently reading (almost finished) “Ice Station Zebra” by Alistair MacLean. He’s been dead for years but I really enjoy his books. They are intriguing political mysteries. Movies have been made from some of his books: “Ice Station Zebra”, and “Puppet on a Chain”, to name two.
Mr. MacLean weaves a good tale of espionage, sabotage, and death, leaving clues to help the reader figure out who the bad guy(s) is. However, like Agatha Christie, he always leaves out one crucial piece of information until almost the very end.
