We're a tad tardy to this one but that only seems appropriate given the circumstances. From the letters page of the May 10th London Review of Books:
"I have just seen Brian Harrison’s 1986 review of my book Victorian Lives (LRB, 19 June 1986). He says my sources were not typical of contemporary prisoners; that I paint too bleak a picture of their experience; and do not recognise the ‘Victorian activism’ of the reformed prison. He is wrong on all three counts.
