In this 77 Sunset Strip episode Roger Smith is investigating a fixed fight where the fix did not come off. The loser who went the distance when he was supposed to dive much earlier was murdered and that is what Jeff Spencer is looking into.
Everywhere he goes Roger Smith gets threats and intimidation, so does Louis Quinn for whom sports betting is the world he lives in. Roscoe has a scene while on a massage table where he's told in no uncertain terms to stop asking questions. The masseur in the scene is former heavyweight contender Lou Nova.
Rhodes Reason plays the former boxer who was the winner of that fight who's feeling heat from all directions. Mary Tyler Moore is his wife. The performance to watch out for is that of middleman Dennis Patrick, a highly nervous sort with reason to be.
Nice shootout at the end, what more could you ask for.
