Goodreads links this author to the American baseball expert of the same name, though this is really by the English author of crime and espionage novels with the same name who does not seem to have his own page on this site.
Worthwhile read for the details of England's security services. Not the average spy plot in that the villan is a colleague of the hero who has stolen a great deal of money from his bosses to invest in a drug running scheme. Interesting for the American reader to get a feel for racism in the UK as the main character is of African descent, and also for the English slang and cultural references throughout. I'm not sure if this is available in the US or not as my copy seems to have been brought over here from the UK, but it's worth tracking down.
