OK....... my parents Sam & Vi Wakefield were the landlord/lady of the Earl Howe at the time of the Fox & Grapes Murder, it is the next pub about 100meters up Carlton Rd. I was about 14 yrs at the time of the murder. Sam & Vi were interviewed several times by the police in the hope that the murderer may have previously visited the EH and they could help with enquiries, obviously a forlorn wish.
I understood from my parents who were Sneinton born and bred that the F & G was nicknamed "Pretty Windows" because in the distant past someone who had been barred for brawling in the pub took exception to the ban and smashed all the pub windows one night after closing time in retribution for the perceived injustice. The nickname for the pub typifies Nottm. city humour which I love some much, I like this explanation and have had no reason to question it these last ~57yrs
