A Study in Terror is a 1965 British thriller film directed by James Hill and starring John Neville as Sherlock Holmes and Donald Houston as Dr. Watson.

By a family crest on the box, they come into contact with the Duke of Shires who admits his elder son Michael Osborne dreamed of becoming a doctor.

Holmes deduces the instruments were pawned to a broker, Joseph Beck, who tells them that he received them from an Angela Osborne, who gave her address as a soup kitchen run by Doctor Murray.

Holmes and Watson meet Murray, also a police pathologist, after convincing Lestrade to let them view the body of the most recent victim, Annie Chapman.

They explain Carfax was blackmailed by a man who threatened to tell his father that Michael, who was helping Murray at the soup kitchen, had married a prostitute.

Murray also reveals his crippled and mentally disabled assistant is Michael, seriously injured as the result of the beating from Steiner, and perhaps the knowledge of what his wife had done.

Holmes and Watson discover Angela in the upper room of Steiner's inn (in reality her property) and she admits that she sent them the surgical instruments, having removed the scalpel herself, to get them involved.

He asks Holmes how he found Michael, and he tells him that he received information from Dr Murray and the woman who owns the Angel and Crown pub.

Henry Lester, managing director of Sir Nigel said "We felt that the royalties we were receiving from various media outlets bore little relation to profits.

[5] A Study in Terror was a co production between Sir Nigel Films and Britain's Compton Group, and American producer Herman Cohen.

"[4] The New York Times said "the entire cast, director and writers do play their roles well enough to make wholesale slaughter a pleasant diversion.

[13] The Holmes-Ripper idea was later taken up in Murder by Decree (1978), in which Frank Finlay reprised his role as Lestrade[4] and Anthony Quayle once again had an important part (though this time as Sir Charles Warren of Scotland Yard).
