During this time, with imported bodyguards from Ireland as well as surveillance by the Serious Crime Squad, McGraw was one of the most heavily protected criminals in the city. He later reportedly brokered a deal with Ferris, with whom he had been feuding for some time over allegations in the latter's first book. It was also reported that McGraw paid Ferris £1.5 to £2 million to keep the peace and make sure Paul Ferris didn't take revenge on him. In the last few years after Ferris was freed from prison, McGraw was said to be spending more time in his villa abroad, with a few of his henchmen.
