I have been a fan of Columbo for as long as I can remember, and I really enjoyed this episode. My only gripes are to do with one or two things that weren't quite as well thought out as another reviewer points out so well, which is the business with the hearing aid and the times that Harvey's character goes back to the hotel room without being seen happened all too easily in my view.
That said, it looks great as you would expect from a standard Columbo episode, the script is still deft and assured and the story is wonderfully paced and always interesting with a final solution that had me completely satisfied. The music is memorable too and fits well with the atmosphere and period, and the direction is tight. The acting is great, Peter Falk is stellar and Laurence Harvey brings a more intense and tormented side to his style of acting which made him all the more riveting.
Overall, a very well done episode. 8/10 Bethany Cox
