Keys, bars, cells, doors, landings, wings -these images of imprisonment are the realities that face Trevor as he begins his sentence in Manchester's legendary jail-Strangeways. Just three days out of Borstal, Trevor experiences the impact of becoming yet another of Strangeways' average population of 1,600. Britain has a larger prison population than any other country in Western Europe. Antiquated 19thcentury buildings, built to deal with half the numbers they now handle, are bursting at the seams. Many men are living three to a cell. Already there have been serious disturbances at Hull and Wormwood Scrubs. Next time it could be worse. Yet everyone agrees that a large number of convicted men now in our prisons should not be there at all.
