Stranger — Bryan Forbes

'Written across the photo were the words To Theo with too much love. One corner was torn, obliterating most of the signature, but I had no difficulty identifying the face. It was a photo of Guy Burgess.' Familiar Strangers is a provocative and compelling novel of betrayal, deceipt and divided loyalties in the perilous world of British espionage, shifting from the Cambridge of the 30s to Franco's Spain, Berlin between the wars, London during the Blitz and the Hollywood of the McCarthy period.
