I watched this the other night because I remember it from when it first aired in the 70s---and it still holds up. Robert Vaughn is a good villain, the British cast is a good counterpoint to Peter Falk's Columbo. You can here a lively version of 'The Mexican Hat Dance' in the middle of the episode (and the closing credits--a good idea by director Ben Gazarra). What I found interesting was the presence of amyl nitrate---back in the 80s this was a drug of choice to stimulate sex. I think they called it 'poppers'. It didn't have this connotation in this episode, since it was filmed in the 70s. But it was funny to see it play an important part of the plot.
