In the brand new three part documentary, The Beverley Allitt Tapes, we will hear from investigators on Beverley's case, her survivors, and the medical professionals looking into each tragic death.

The series will also look back on the murderer's seemingly normal childhood, in a bid to understand why she did what she did, with witness and expert testimony.

While there have been multiple docs about Beverley in the past, this one offers brand new, unseen police interviews with Beverley.

It also looks back at news archives from the time, and includes forensic expert analysis "in a bid to understand the psyche" of one of Britain's most evil killers.
