This plot wasn't a cliche in 1975: mob hitmen use vulnerable office employee to obtain the wherebouts of "participants" in the government Witness Protection Program.
From "Police Woman"s most 'serious' period, where the show was really genuinely striving to be "good", the episode is enhanced by Richard Shore' forboding music score, and the work of somewhat-legendary cinematogrpher, Gerald Perry Finnerman ("Star Trek"/"Moonlighting", etc..)
