My wife worked for years as assistant cook in the officers mess ,then in charge of a Mrs Amy,some times "trainees"were allocated to the mess as helpers,she told me many a strange story,somtimes comical ,somtimes tragic of the boys she met there,my wife was not employed byHMPrisons but by the officers mess committee,So she had no official connection to the prison.
We have been divorced now for many years,but I still recall the tails I was told,never to be divulged.😎
