"The reader will notice that there are now half a dozen blank spaces
in the organizational charts," writes Allason in his introduction to The
Circus. A senior MI5 officer stole his manuscript in 1982 and obtained an
injunction against publication. But by then the manuscript had already
reached U.S. publishers, so British censors were willing to negotiate.
Even with the deletions, one has to agree with Allason that "this final
version of The Circus is the most detailed account of MI5's work ever
published, or ever likely to be."
