The Man Who Was Sherlock Holmes (1937)

A spoof of the entire 1940s detective genre. San Francisco private detective, Lou Pekinpaugh is accused of murdering his partner at the instigation of his mistress—his partner's wife.

In 1947, long-retired and near the end of his life, Sherlock Holmes grapples with an unreliable memory and must rely on his housekeeper's son as he revisits the still-unsolved case that led to his retirement.

High society sleuths Nick and Nora Charles run into a variety of shady characters while investigating a race-track murder.

During WWII several murders occur at a convalescent home where Dr. Watson has volunteered his services. He summons Holmes for help and the master detective proceeds to solve the crime from a long list of suspects including the owners of the home, the staff and the patients recovering there.

The roguishly charming and endlessly troublesome Fletch becomes the prime suspect in a murder case while searching for a stolen art collection. The only way to prove his innocence? Find out which of the long list of suspects is the culprit - from the eccentric art dealer and a missing playboy to a crazy neighbor and Fletch’s Italian girlfriend. Crime, in fact, has never been this disorganized.

When an upwardly mobile couple find themselves unemployed and in debt, they turn to armed robbery in desperation.

When Watson reads from the newspaper there have been two similar murders near Whitechapel in a few days, Sherlock Holmes' sharp deductive is immediately stimulated to start its merciless method of elimination after observation of every apparently meaningless detail. He guesses right the victims must be street whores, and doesn't need long to work his way trough a pawn shop, an aristocratic family's stately home, a hospital and of course the potential suspects and (even unknowing) witnesses who are the cast of the gradually unraveled story of the murderer and his motive.

The crooks in London know how it works. No one carries guns and no one resists the police. Then a new gang appears that go one better. They dress as police and steal from the crooks. This upsets the natural order of the police/criminal relationship and the police and the crooks join forces to catch the IPOs (Impersonating Police Officers), including an armoured car robbery in which the police must help the gangs to set a trap.

Now a detective-for-hire like her infamous brother, Enola Holmes takes on her first official case to find a missing girl, as the sparks of a dangerous conspiracy ignite a mystery that requires the help of friends — and Sherlock himself — to unravel.

There is a new criminal mastermind at large (Professor Moriarty) and not only is he Holmes’ intellectual equal, but his capacity for evil and lack of conscience may give him an advantage over the detective.
