Strange Partners The Invisible Man : Season 1 Episode 13

After his bag of documents was stolen, Brady is kidnapped by a mysterious man who wants him to commit a murder - and to keep the unseen Brady in check, he has a vicious guard dog who can sniff out and catch even an invisible man. The potential for invisible mischief again crops up here, with the rather inventive concept of a dog being used to keep the scientist in check, even when completely invisible. Well paced and very dark it does leave the viewer wondering why there are not easier ways to have a man killed than kidnapping the Invisible Man. It makes for a decent conclusion to the first season.
