From The Perry Mason TV Show Book
This boozy, off-center episode has Perry rather unbelievably representing a citizen’s group in hearings on a proposed aqueduct to be named after county engineer William Harper Caine. There is some question as to the acceptability of the proposed route, and Perry gets a stop work order until a section of Manzanita Canyon can be checked for an underground spring.

But this story has more to do with murder than drainage. Eventually, Caine needs Perry’s help when Roger Quigley, the project’s chief contractor, is murdered.

We get a good look at just how fast Paul can be on his feet. During the investigation, the detective is nearly seduced by a rum-soaked floozy and breaks the record for the 100-yard dash to escape her clutches.
