For over 30 years Paul Maleary worked as a Detective for the Essex Police, investigating criminal cases and horrific murders. Darren Stanton spent his time dealing with liars, cheats and criminals as a former British Police Officer. The preparation for a police interrogation is enormous but it's important to gain as much evidence as possible to reveal the lies or the truth. Rob Rinder’s Interrogation Secrets takes a unique look at the battle of wits between police and suspects in some of the most disturbing US and UK criminal cases in recent years. The series is presented by criminal barrister and television personality Robert Rinder, whose legal background makes him the perfect guide to the dark arts of interrogation.
