In the Manner of Sherlock Holmes (1956)

A horrific and, on the face of it, incomprehensible murder has just been committed on the unsympathetic person of a loan shark. The victim's body is found lifeless, but the circumstances of his death are far from clear. For want of anything better to go on, the police immediately suspect a penniless gentleman who had the bad idea and misfortune to be present at the time of the crime. The police don't take the time to look for other possible suspects, and are not at the end of their surprises. A dark story seems to lie behind this imbroglio of incoherent facts.
