Hannam became famous for solving the infamous Teddington Towpath Murders in 1953.
Adams was only charged with two though, the murders of Edith Alice Morrell and Gertrude Hullett. He was tried for the former in 1957 but controversially found not guilty. The Attorney General entered an unprecedented plea of nolle prosequi regarding Mrs Hullett.
Hannam expressed concern about not only high level political but medical and judicial interference in the investigation and the subsequent prosecution. 
Hannam was later promoted to Commander but left CID in 1960, becoming a security adviser.
