</p>
<p>‘Powerfully illuminates what it was like to live under a genocidal regime’</p>
<p>
<strong>Kathryn Hughes, <em>Guardian</em></strong>
</p>
<p>‘As much about the process of investigation as about the subject investigated. Along the way [Sullivan] lucidly describes many fascinating details of the compromises and betrayals of life under a murderous regime’</p>
<p>
<strong>Craig Brown, <em>Mail on Sunday </em></strong>
</p>
<p>‘Sullivan circles all of the possibilities like Agatha Christie with Zoom and a time machine. Shaped like a procedural or a whodunit, <em>The Betrayal of Anne Frank</em> hums with living history, human warmth and indignation’</p>
<p>
<strong>
<em>New York Times</em>
</strong>
</p>
<p>‘Featuring startling new revelations and an intriguing new theory of what happened’</p>
<p>
<strong>Daniel Finklestein, <em>The Times</em></strong>
</p>
<p>‘Praiseworthy. With impressive clarity and dramatic effect, Sullivan reconstructs a complex investigation lasting five years’</p>

<strong>Gerard de Groot, <em>The Times</em></strong>
</p>

<p>
<strong>
<em>Press Association</em>
</strong>
</p>
<p>‘Meticulous … Sullivan describes the Cold Case Team’s interdisciplinary methods, from criminal profiling, historical research and crowdsourcing to a Microsoft artificial intelligence program that found connections within a blizzard of archival documents. But the book is most engrossing as a portrait of wartime Amsterdam, a city of conflicting and cross-cutting loyalties, where personal peril could erase the line between heroism and villainy’</p>
