I know, there have been found seely boores, who have rather endure to have their feet broiled upon a Greedyron, their fingers ends crusht and wrung with the lock of a Pistoll, their eyes all bloody to be thrust out of their heads with wringing and wresting of a cord about their foreheads, before they would so much as be ransomed.

Just north of Farringdon station, and to the east of Ray Street, there is a wide cutting bounded by another of those brick walls nicely calculated to be just too high for you to see over. So prop your bike against it, and stand on the down-pointing pedal crank. You are looking at the Ray Street Gridiron, a spectacular bridge in a cutting that carries the Metropolitan, the supposed Underground, over the Widened Lines (now Thameslink).
