Charlie Muffin (published in the United States under the title Charlie M.) is a spy thriller novel written by Brian Freemantle. The book was published in 1977. Synopsis Charlie Muffin is one of the top operatives in British Intelligence, despite his working-class background and scruffy appearance, and has been responsible for breaking up a major Soviet spy network in England, sending the network's leader Alexei Berenkov to prison for forty years.

Charlie visits Berenkov, with whom he has apparently become friendly, in prison for an interrogation which appears to Cuthbertson, his deputy Wilberforce, Snare and Harrison to be a complete failure.
