The mouse and cheese is "Agenda For Murder." The guy wrapped up in a towel looks like he has a toothache, so that would be "Uneasy Lies The Crown." Good old Wes Corman!!!
The murderer in "Murder In Malibu" was a professional tennis player. Remember? He was supposed to be away at some major tennis match when the murder took place.
Thanks. I'm a little rusty with the ABC episodes...I don't have them on tape, and I haven't seen them since they were on the Family Channel a few years ago.
