Who likes crime shows?

I need TV recs, oh wise flist.

I went over to my buddy Frank's this afternoon, and he showed interest in getting some new TV shows to watch. He goes to bed at 7 o'clock because there's nothing on TV and he has nothing better to do. He's widowed and lonely and bored. He's 83, but he has a DVD player, so whatever the Internet can provide, I can burn.

He likes crime shows - detective things like Jonathan Creek, Morse, Poirot, Miss Marple... but not so much CSI because of the bad language. His eyesight is failing, so no subtitles or reliance on subtle visual clues, but he's sharp and intelligent, and entirely with it brain-wise. He's an absolute sweetheart and I love him like he was my own grandpa (he's Claire's) and I want to be able to do something nice for him. I'll be seeing him for our weekly lunch tomorrow, and it'd be great to have some ideas by then. I was thinking maybe Dexter? Hustle? But really I'm stuck. I'd like to take half a dozen pilots for him to try out.

???!
