Some of these people found their way into positions from which they convinced Churchill and others who knew better, or should have, that Tito's forces were doing a better job against the NAZIs than Mihailovich's. This included giving Tito credit for Mihailovich actions and victories!
Result: Mihailovich was starved for support, while Tito received lavish praise and help. Of course, it is also well documented that Tito used this support to fight and destroy Mihailovich's forces on many occasions.
It is also very likely that Tito's image of "independence" from Moscow was ALWAYS actually a clever Soviet canard.
Yes, there are some excellent books on the subject, including The Web of Disinformation by David Martin and The Rape of Serbia buy Michael Lees. The British agent in charge of all the WWII intelligence coming in from Yugoslavia was James Klugman, who also turned out to be the communist recruiter at Cambridge University who recruited the infamous Soviet spies, Burgess and Philby.

Actually Kenny, I think that the break between Stalin and Tito was more about egos. Stalin wanted Tito as a worker-bee for greater Russian commuinsm and Tito wanted to be "the Stalin of the Balkans". Much of what has happened in the break-up of Yugoslavia can be attributed to Tito's failed plans for spreading communism throughout the Balkans, including Tito's pre-Hoxha plans for taking over Albania. Tito also supplied the communist side of the post-WWII Greek Civil War.
Tito’s independence of Moscow was solidified in 1948, especially with the removal and execution of those who sided with Stalin in Yugoslavia during the Informbiro scandal.
