'New Scotland Yard Files' Airs Tonight

Presented by former New Scotland Yard detective, Peter Bleksley, the series hears from police officers, forensic specialists and journalists to find out how some of the most notorious killers were caught and put to justice.

The docu-series explains how the experts approach each case by following "the ABC of the detective world" which means they accept nothing, believe nobody and challenge everything.

The second episode of the series will air tonight and will focus on the murder of 29-year-old Nisha Patel-Nasri, a popular hairdresser and special constable who was fatally stabbed in her home in London.

The night before the attack, tragically, Nisha had just celebrated her third wedding anniversary, with lead detective on the case, Nick Scola, explaining he was "mystified" over what the motive behind the killing could be.

With no evidence, no forensic findings and no murder weapon, police were desperately seeking a breakthrough and doing everything they could to uncover new details.

When detectives eventually made progress in the case, a heartbreaking and shocking web of secrets and lies were revealed which eventually led to an arrest and a conviction.

New Scotland Yard Files also delves into the murder of David "Sinders" Morley on London's South Bank, the case of the Stockwell Strangler who targeted elderly men and women, and the murder of former pop star Michael Menson.

Alongside police and detectives on the cases, viewers also hear from journalists who covered the stories as they unfolded and criminologists who analyse methods and motives of murderers.

While the second instalment will be on telly tonight, each new episode airs on CBS Reality, every Thursday at 10pm.

We're definitely setting a reminder for this one...
