"Dangerous Gambit" marks the third time Gary Lockwood would appear on "Barnaby Jones".....and in total he was on the program six time! He generally played vicious villains....even more so than the usual characters on the detective show.
In this episode, two women are robbing their own bank. However, as one of them is leaving the bank, she sees Jerry (Lockwood) and panics...running into the road and being killed by a passing car. Barnaby is called onto the case because the driver is insured by Barnaby's client...and his job is to determine liability...and ends up exposing a robbery that the bank never knew had happened!
The most interesting casting choice was Linda Henning as one of the thieves. She had previously played Betty Jo for years on "Petticoat Junction"...a far cry from being a bank robber!
So is it any good? Yes. It's not an outstanding episode but solid and enjoyable.
