Some of Alastair Maclean’s work revolves around espionage or police work. I always liked Ice Station Zebra (the book - the movie bares virtually no resemblance to it) and some of the short stories in “The Lonely Sea” are espionage based.
He did some stuff I really liked, but he starts doing badly with The Way to Dusty Death.
Goodbye California with the nuclear bomb ticking…ugh
An enthusiastic second for Daniel Silva. I’ve just gone through about five of his books, even though it’s been ruining my sleep schedule.
