I totally love this episode and give it five stars, (if that's the highest level). It is really fascinating the way they have the story play out from both points of view, with flashbacks and different people's testimony. This has always been a favorite episode of mine, (although I have lots of favorites). This one is one of the most interesting episodes in the series. I love the way they leave you guessing who did it at the end and they never tell you, but it's frustrating at the same time. 

I am not sure who is guilty, but I tend to side with Howard, the accused. Something about his tone of voice when he says he was innocent at the trial sounds genuine to me and the wife sounds like she is hamming up her testimony. I get the feeling she is acting because she is overly dramatic and the man (Howard) sounds genuine to me. Also, there is one point where she hesitates in what she is saying and I get the feeling she is lying. However, I could be wrong. That's what makes this episode so interesting. You can listen to it again and change your mind, or hear details you didn't notice before. I could listen to this one many times and it wouldn't get boring and I might never have the answer as to who is guilty. A true classic, in my opinion.
