Inside Scotland Yard with Trevor McDonald. Two-part documentary in which Trevor McDonald gains unprecedented access into the Metropolitan Police's headquarters, exploring landmark investigations as Scotland Yard moves to a new home. In this edition, Trevor meets former DI Paul Bickley at the notorious crime museum - dubbed the 'black museum' by the press - which was created in 1875 and contains grisly items such as body parts, nooses and murder weapons. He explores the crimes of George John Hague, known as the Acid Bath Murderer, and sees how body parts and dentures were recovered from the scenes of the crimes in 1949. Trevor also unearths police disciplinary records dating back to 1829, finds out about early policing forensics, DNA, fingerprinting and early surveillance techniques. He meets Helen Pankhurst, great-granddaughter of Emmeline, to find out about how Scotland Yard dealt with the suffragettes and the surveillance techniques that were used.
