Why These Connect
The narrative assertion
"The servant's strangulation in the opening scene (a servant in a white coat is strangled in the corridor) is confirmed as murder by the Doctor's discovery of the lifeless body of the same man in a cupboard. This establishes the immediate danger and confirms the sinister plot is already active."
About Causal Connections
A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
