The Daily Telegraph wrote that "Philby's story has of course been told many times, but this programme reminded us why: because it's completely irresistible. Not only does it startlingly combine the personal and the worldhistorical, but it also reveals the British class system in all its tragi–comic pomp. The programme reconstructed their conversations rather in the style of a
Stephen Poliakoff drama". British journalist
Andrew Billen noted that "it was of course, a story hard to tell badly, but for once in an historical documentary, the re-enactments felt right ...the film's gimmicks were witty even when unnecessary ... and as
E. M. Forster once said, he would rather betray his country than his friend ... Philby, more reptile than primate, did both". Television critic
Clive James, opined that while "the story of Philby is inherently fascinating, the half documentary, half drama format chosen for the show drained the action of all narrative force. Only some of the blame could be assigned to the on–screen narrator, Ben Macintyre. Utterly undynamic in personal appearance, he might, if used sparingly, have functioned as a piquant contrast between our everyday lives as free citizens and the suffocating milieu of the traitors who gave their allegiance to tyranny. Alas, the show's producers chose not only to make Macintyre himself the central figure, but they sexed him up with a hat, a coat and briefcase all meant to evoke espionage. The results were unintentionally hilarious, and I spent a lot of time groaning and yelling". Tom Birchenough of
The Arts Desk said "David Oakes as Philby made us understand the man's charms, not to mention his verve, as he outplayed the rather nerdy Nicholas Elliot, portrayed by William Beck". In his review for
The Independent, Will Dean states the series is "told in an odd smorgasbord of formats. There were reconstructions of Philby and Elliott's conversations played by actors. Then there were other sort-of reconstructions in which Macintyre himself performed the roles of various characters". Dean says that in the end though, it is "Macintyre's narrative that paints Philby – thoroughly – as a very English traitor". Euan Ferguson of
The Observer wrote that "journalist Ben Macintyre, who has unearthed all this, paced the two nights of the series with just the right recipe of pop-cultural intrigue and erudition". ==Episodes==
