It is much more than a history of bureaucratic crime. Rather, Gretton has written himself deeply and intimately into the work, which also serves as a poignant memoir; a travelogue that leads the reader through time and space, history and memory; and an extended exercise in observation and introspection. --Jonathan Kirsch, The Washington Post

Remarkably powerful . . . [a] compelling and modern investigation of the collective amnesia which so often operates in the telling of national histories, including our own. --Mark Cocker, The Spectator (UK)

A complex and exceptional book. Gretton's determination to bear witness so long after the events themselves does not diminish the power of his story. On the contrary his decision to make it personal intensifies the impact. --The New Statesman (UK)

Gretton raises profoundly unsettling questions about the capacity for doing evil that exists within all of us, and the ways in which the distancing effect of technology allows perpetrators to avoid thinking about the consequences of their actions. --Hugh Linehan, The Irish Times

The writing has the power at times to mesmerise . . . Gretton is a brave man to have stared so long and intently at the subject. --Ian Thomson, Evening Standard (UK)

I You We Them is a uniquely gripping journey around the landscapes of mass murder. --Philippe Sands, author of East West Street: On the Origins of Genocide and Crimes against Humanity

"Great books never occur out of a desire for greatness, but often out of a possessed persistence in the face of a chosen and immensely difficult task. I You We Them is such a book. In it, though, a century speaks to us--not with the thunderous voice of history, but in the intimate voice of a sequence of confessions." --John Berger, author of Ways of Seeing

A book of extraordinary importance and urgency - we need this book now. For its determined, passionate, and vulnerable seeking; for its insistence on what matters. Climate catastrophe tells us the reach of the desk killer has never been greater. We must take the hope and political will in this book as our own: forged in darkness and therefore inextinguishable. --Anne Michaels, author of Fugitive Pieces

Not since Gitta Sereny's vast script of Into That Darkness arrived on my desk have I read anything so disturbing as the draft of Dan Gretton's book... much more alive than anything I've read for ages... I'm certainly grateful for having been given the chance to read this amazing work." --Diana Athill, author of Somewhere Towards the End
