The Seventh Man: My Part in the Defection Scandal
by Geoffrey T. Alsop, as told to Graeme Garden (Eyre Methuen, 1981)
Judging from this clever satire on official deniability, in which a senior MI6 operative misinterprets and overlooks at every hapless turn (and even unwittingly participates in) the now-infamous defection of British diplomats Burgess and Maclean, Graeme Garden should have written more novels.
