Letters to the Serjeant at Arms Department
Judging from his Occurence Books, Inspector Denning reveled in the administrative side of his role going beyond the call of duty to jot down every last detail in case it may be of importance at a further date. In this 1883 letter, he's writing to the Serjeant at Arms requesting additional policing within the Palace of Westminster, probably as a result of nefarious groups who sought to cause some form of civil disobedience in this tumultuous period. It's a great example of the diligence that Denning was renowned for as he made special specifications for greater security around the debating chambers which he felt was an area of great vulnerability to the members.
