People who handle money and work alone are especially vulnerable to robbery with violence and murder. High on that list are taxi drivers. So it was that Ivor Pearce, 30, an Edgware, London, cabbie, was found slumped over the wheel of his taxi in Warren Lane, Stanmore. He had been shot in the back of the head with an automatic pistol.

Mr. Pearce was a “cover-driver,” who only worked occasionally on a casual basis. He took his last fare that night, Friday, December 17th, 1965, at 11.30 p.m. in the West End.

Some mystery surrounds the murder. The police received several mysterious letters about the case, suggesting Mr. Pearce may have known his killer.
