I'm not a lover of spy novels, yet I adored this book. What Macintyre reveals - but not too quickly - is the extent to which those who confided in him, as friends or colleagues or both, were made unwitting accessories to treason * Evening Standard * at least as compelling as any of the great fictionalised accounts of Britain's greatest traitor and one of the best real-life spy stories one is ever likely to read ***** * Daily Express * It reads like fiction, which is testament to the extraordinary power of the story itself but also to the skills of the storyteller. To read A Spy Among Friends is a bit like climbing aboard a runaway train in terms of speed and excitement - except that Macintyre knows exactly where he is going and is in total control of his material * Daily Mail, Books of the Week *

No one writes about deceit and subterfuge so dramatically, authoritatively or perceptively. An engaging book on a tantalising and ultimately tragic subject, If it starts as a study of friendship, it ends as an indictment * Philip Hensher, Spectator *
