‘This excellent book contains lessons that are still valid in the 21st century’ – Oleg Gordievsky on Dead Drop

‘Duns’s terrific debut will draw inevitable comparisons to early John le Carré, though the lead character, turncoat British Secret Service agent Paul Dark, is a complete original… Seldom has a thriller plot taken more unseen turns’ – Publisher’s Weekly on Free Agent (starred review)

‘A retro-cool romp as spare of prose as it is cleverly convoluted of plot. Duns has ingeniously caught both the spirit of an era and the spirit of the books which made that era the golden age of spy fiction.’ – The Daily Telegraph on Free Agent

‘A treat for fans of traditional Len Deighton-style thrillers.’ – The Guardian on Song of Treason

‘The key to Duns’ success is his ability to pen high-energy, enthralling action sequences allied to an impressive attention to detail, transforming the traditional spy classic into a compelling mirror of real-life history and politics... Breathtaking in its veracity and power.’ – The Lancashire Evening Post on Spy Out The Land

‘A taut and tortured exploration of betrayal on the national, ideological and personal levels simultaneously… A cleverly twisted tale of intrigue and deception, this is a masterly excursion back to the bad old days of the Cold War.’ – The Times on Song of Treason

‘A wholly engrossing and sophisticated spy novel set against a forgotten corner of 20th-century history. Fascinating and compelling.’ – William Boyd on Free Agent

‘The immediacy of Duns’ writing grabs and suspends the reader in a beautifully realized heartbeat of recent history.’ – Kirkus Reviews on The Dark Chronicles
