The taxi driver’s fare, resplendent in RAF uniform, wanted to be driven from New Street Station, Birmingham, to Derby, 40 miles away – which must have seemed odd to cabbie George Tyler, because there were plenty of trains going to Derby that evening of Monday, APRIL 28th, 1947.

Next day Tyler was found dead in his cab at Clay Mills, on the A38 Derby road. He had been shot three times and robbed. Police interviewed more than 1,000 RAF personnel but the killer was never found.
