Derek Creighton "Bertie" Smalls (1935 – 31 January 2008) was considered by many as Britain's first supergrass. Although there have been informers throughout history – the Kray twins were partly convicted two years before Smalls on evidence given by Leslie Payne – the Smalls case was significant for three reasons: the first informer to give the police volume names of his associates and provide the evidence that would send dozens of them to prison to serve long sentences; the first criminal informer to strike a written deal with the Director of Public Prosecutions; the only criminal informer to serve no time for his crime in return for providing Queen's evidence.
