Adrian Robinson is not at the above co-ordinates. He is Doctor No's driver and is responsible for stealing the second page of the "Numbers Letter" from the Royal Academy archives. Before leaving No 9 Downing Street, Moneypenny passes you a file, marked for your eyes only, containing the first page of the letter and a note locating Robinson at N 52º 22.(A-2)(B-1)2 W 002º 00.(C-A-2)D4 where 2Ath April 1BCD is the day on which the author of the letter was born.
There is nothing at the listed coordinates. You don't need to defect to the other (more dangerous) side to find Adrian Robinson.
