There are only two shows that I'll put books down to watch: ABC's Castle and The Unusuals. They're both great shows.
Castle is about an author in need of a muse, and ends up hanging around with NYPDs Detective Kate Beckett.
The Unusuals is about the quirky, and dangerous events that happen to detectives, personal and on the job. In addition to being a good show, it has excellent music.
I can't find the song played at the end of last night's show, but I did find this one from a previous episode.
