So I recently read the June 2011 Mobile Read Book Club selection,
The Maltese Falcon by Dashiell Hammett. Meh

. I also recently read a couple of the nominated books that did note win the vote. The
Spies of Warsaw by Alan Furst that I found to be an excellent espionage novel. Also
The Spy Who Came in from the Cold by John le Carré, once more excellent. Though for the last I probably would have enjoyed it more if I had not already seen the film a number of times. I thus already knew the plot, including the twist ending. That and however le Carré wanted the reader to envision Leamas, I could not imagine anyone but Richard Burton.
Anyway what I wanted to ask is this. A number of years ago I watched a few episodes of a British TV series about another Cold War spy. I am fairly certain that the hero, a British intelligence agent, was named “Muffin.” Seriously

. I am wondering if this was based on a book? I thought it might be an alternate character, to George Smiley, of le Carré's. Not so though. Any intelligence

on this matter would be much appreciated.
