One of the weaker episodes from the detective series' otherwise sterling first season concerns an unknown, disgruntled cruise ship employee who is killing off innocent passengers, thereby giving the cruse-line a bad reputation and putting them in financial straits. Charlie warns Sabrina, Jill, and Kelly that taking on this assignment--as passengers, and potential sitting ducks--may be the most dangerous mission they've ever had...the ladies even vote whether or not to accept! They do, but new identities are not needed: someone pins a dummy with a warning message to the office door (which is never cleared up by the end, but never mind). The writing here is so thin that there's really no question who the maniac is, but the Angels still look good in their bathrobes rushing around shipboard corridors with their guns drawn. That's the main appeal here, not the camp-twist with Frank Gorshin as a clairvoyant and celebrity impressionist. Gorshin seems to think he's mining Emmy gold with this hammy performance, and the camera just sits on him while he goes into his schizoid arias. Jaclyn Smith (in an all-black leotard) gets to play dead at one point, which is fun, and Bosley's brief encounter with the killer leaves him stripped to the buff. The big finale involves three very intricately-designed time bombs (one for each Angel to diffuse!), but no one ever asks how the killer managed to construct such devices, not to mention bring them aboard ship and hide them in strategic places. For that matter, how exactly do doors open and close (and lock) all by themselves, and why doesn't one unfortunate couple do what Kelly does when the doors shut: climb up through the ceiling? The likable camaraderie between the Angels keeps this episode together. Really, you can't fake chemistry on the screen--the camera is too sharp--and Kate Jackson, Farrah Fawcett-Majors and Jaclyn Smith appear to have a friendship that goes beyond turgid scripts like this. They transcend the tackiness, although this episode nearly leaves them all at sea.
