ON THE DAY Dai Brainbocs arrived in Shrewsbury Prison Frankie Mephisto sent for him and explained the situation. He told him they didn’t like bookworms and eggheads in prison and that without protection the frail schoolboy genius would be dead within months. And Frankie was the only man who could provide the necessary protection. That’s when he made the offer. He told Brainbocs he had one dream left in life, and that was to visit Aberystwyth before he died and hear Myfanwy sing at the Bandstand. But, as everyone knew, Myfanwy was dying and would never sing again. You must make her well, he said. You will be put in a cell at the top of the tower overlooking the railway station. You will not be disturbed. But neither, in the manner of Rumpelstiltskin, will you be allowed to leave the cell until you have found a cure. Whatever books or scientific equipment you require will be made available. Brainbocs accepted the proposal. He said the offer of scientific equipment would not at that stage be necessary. It was his opinion that in the matter of probing the ineffable mysteries of life, disease and death there existed no finer scientific measuring scope than a gentleman at stool. And so he ordered a new chamber pot - size 7 - and went to his tower.
