My family used to watch "Murder She Wrote" in it's first seasons. Since then, if it is on TV during lunch, I will have it on in the kitchen. So while I have not seen every episode, I have seen enough, I feel, to rate this one.
I sought this episode out to see Patrick McGoohan's performance. It is always a treat to watch him, even if he isn't in his best roles. Here we get to hear his British accent, but it is a wee-bit over the top for a story taking place in Canada. Still, his unique speech pattern is still a joy to hear. And he adds humor to the show. (Long-time McGoohan fans will chuckle at the mere idea of Oliver Quayle's telephone calls with his multiple ex-wives.)
Alas, there is not much else here that is any good. Plot is weak, acting is horrible. Even Lansbury seemed to have "phoned it in" this episode. Again, while I haven't seen every episode, I have seen enough to say this one is a stinker...
