People did try to help Mr Trebus. Nobody was able to get through to

taken it upon himself to help Mr Trebus but even he gave up.

That man was a self-styled entrepreneur, if I remember right, and was
certainly not a mental health professional.

His neighbours were extremely tolerant considering the health hazard.

Oh absolutely! I have no doubt that it was a terrific hazard and the smell
must have been awful but the people sent to deal with it were only ever
going to clear the effects, not the cause.
