Morris West was one of the best-selling novelists of his time, and several of his books were turned into highly successful films, notably 'Shoes of the Fisherman' and 'Devil's Advocate.' This novel was written later, in 1976, and it stands up amazingly well almost 50 years later. I've found many books from the time are now quite dated in either style, characterization, or plot - and sometimes all three. (See my recent review of Robert Ludlum's 'The Gemini Contenders, written 1974, for example.) But West was an expert stylist and his stories less rooted in WWII and/or the Cold War than those of many of his contemporaries. In fact, this story revolves around the emerging unholy alliance between banking, computer networks, and the collection and sale of personal information. More than a little prescient, and strikingly so.
One of the more interesting aspects of this book, from a writerly perspective, is that the 1st-person narrator is not the protagonist of the story. This is not a new technique (think Holmes and Watson), but West does a masterful job of giving both lead characters a compelling arc and ever-deepening relationship from start to finish.
All in all, I still give this 4 stars, and will put it back on the shelf for another read some day.
