I see Columbo every sunday on the Hallmark Channel at 12am before that I see matlock and before that their is always a Perry Mason Movie on which I watch also. Hallmark also had other mystery movies which stars John Larroquette from Night Court and the red head who played Micheal J. Fox mother on the Back To The Fure Movies. So if you have to have your Columbo fix or mstery fix just watch the Hallmark Channel and you will be satisified

But Damian we don't get the Hallmark channel....

One way to find out, at least in the USA, is to go to Yahoo.com and click on TV. They have a feature that lets you enter your ZIP code and cable (or other TV service) info, and then you can "search listings" for the next 2 weeks -- for example, you can search throughout your own available channels for "Columbo".

TV Guide.com has a similar feature, but their site got so unreliable that I now prefer Yahoo.

If it helps at all, I have seen the older episodes aired on WGN (the superstation out of Chicago that runs on a lot of cable systems). They run a lot of McCloud, McMillan & Wife, and all those other old ones. When or how often, however, I cannot say.
