Seven Murders for Scotland Yard (1972) on Netflix

Plot summary

A number of call girls are turning up brutally murdered in London, and the police nickname the unknown slasher Jack the Ripper, after the notorious killer of the late 1800s. Inspector Henry Campbell leads the hunt for him. Bruno Doriani is an ex-acrobat who has a bad limp from a trapeze accident years earlier; his life has slipped, and he passes his nights in seedy bars and with prostitutes. He knew one or two of the dead women, so the police look at him as a suspect. The killer also has cannibalistic tendencies, and Scotland Yard wants the murders solved quickly.
