Why read this explainer

Compare the short murder-watch premise with the added romance and neighbors. Lisa and Stella make Jeff's observation part of relationships that become endangered when Thorwald crosses into his room.

PlotGeeks note

Thorwald entering Jeff's room collapses the distance on which the watching depends. Expanding the romance and neighborhood gives that crossing consequences beyond the isolated detection problem.
