They had met at Crystal Palace, a van pick-up with Mendel driving. They drove to Barnsbury, straight into a car-body repair shop at the end of a cobbled alley full of children. There they were received with discreet rapture by an old German and his son, who had stripped the plates off the van almost before they got out of it and led them to a souped-up Vauxhall ready to drive out of the far end of the workshop. Mendel stayed behind with the Testify file, which Guillam had brought from Brixton in his night-bag; Smiley said, “Find the A12.”
