Thanks very much for your report. Really interesting to read about your evening.
I am so glad you could get some time without the pubs being open.
Also fascinating that you got some audio of cell doors opening and closing, there are no other doors that sound like those. Also of interest because it was sounds of the cell doors opening and closing and footsteps that Mr Seymour says he heard when he was locked up overnight in the cells back in the early 1960s, and which convinced him the cells were haunted.
St Neots Museum
Listen clearly as the sound of a door lock can clearly be heard moving, but no one is there and the locks were all checked and nothing was found.
